『 Hardware ⊙ packing piece 』

▲ The packing box of Xiaomi bracelet is missing, so this picture is from the network. millet Bracelet The environmental protection paper material unified by Xiaomi family is used, and now more intelligent wearable devices use this kind of material packaging box.

▲ The BONG2 bracelet is packed in a plastic box and opened with a zipper. It looks very classy.

▲ The i5plus bracelet uses environment-friendly kraft paper packaging box similar to the Xiaomi bracelet. The outer package is simple and generous, with only the iwown logo. In addition, the cloth pull ring is also carefully designed for easy opening.

▲ The Misfit Flash bracelet only uses a thin paper leather packaging box, which looks inferior. It may be because American products conform to foreign eyes.

『 Hardware ⊙ Appearance 』

▲ Xiaomi from left to right Bracelet 、 BONG2 bracelet, i5plus bracelet, Misfit Flash bracelet.

▲ millet The appearance of the bracelet is simple and fashionable, and the body and wrist strap are designed separately The wrist strap has a variety of colors to choose from, which can be matched with various clothes 。

▲ BONG2 also adopts a separate design, but its appearance is quite different from that of the Xiaomi bracelet. The front and back sides of the body are made of metal. The front of the bracelet has only one YES key and a circle of LED lights around it. The synchronization and other control functions of the APP are controlled by the YES key, and the LED light is used to display the status.

▲ The i5plus also adopts a separate design. Unlike other bracelets, it is equipped with 0.91 inch touch screen It can display time, application reminder and other functions, and related information such as movement and sleep can also be displayed on the screen. And the fuselage is equipped with USB interface, which can be used for charging.

▲ The Misfit Flash bracelet is also in a separate design, made of plastic material, and is more colorful than other bracelets.

『 Hardware ⊙ main part 』

▲ The front of the main body of Xiaomi bracelet is a piece of metal, which hides 3 LED lights, details It's handled very well. It feels very comfortable. The bottom is plastic and feels comfortable. The back is printed with millet logo. There are Two metal shocks can be charged with a special charger.

▲ The main body of BONG2 bracelet is oval and made of metal, but the workmanship is not satisfactory. There are many burrs on the front, so it can cut hands. The processing around the bottom is relatively smooth, the bracelet is acceptable, and the details are also well processed. The bottom is printed with the BONG logo and the name of the design company.

▲ The main body of the i5plus bracelet is rectangular, the body line is good, the arc of the corners is properly handled, and the handle is good. The front is 0.91-inch glass screen, the bottom is also made of plastic, and the body has no Angstrom identification. The bottom of the fuselage is equipped with a convex buckle combined with the wrist strap, and one side is equipped with a USB plug for charging.

  ▲ The main body of the Misfit Flash bracelet is round, all of which are made of plastic materials with bright colors. There are 12 LED light beads hidden on the front of the fuselage, through which the time and movement completion can be displayed. And the whole body is a button, which displays relevant information by pressing.

『 Hardware ⊙ Wrist strap 』

▲ millet Bracelet The wrist strap is made of American Dow Corning TPSiV material, which is very comfortable and textured. The surrounding treatment is also very meticulous. The round hole is made of laser micro perforation. However, this wrist strap is relatively resistant to dirt. When wearing it, one side of the wrist strap buckle passes through the ring buckle and is buckled into the round hole on the other side. The clasp is thin, and the clasp of the author has been broken in half, but the wrist strap can be purchased in major e-commerce.

▲ The design of the BONG2 wristband is the same as that of the Xiaomi wristband. It is thinner than the Xiaomi wristband, with ripples on the inside, which is convenient for water drainage and sweat drainage. However, the texture of BONG2 wrist strap is hard, but it is more elastic than Xiaomi wrist strap. The author tried to pull the ring buckle of BONG2 without breaking it. However, the official does not provide the purchase service for the wrist strap. In case of breaking, no replacement source can be found.

▲ The wrist strap of i5plus bracelet is made of special TPU (food grade), soft and thick. The surface is slightly frosted, and the touch is comfortable. The metal buckle used has the iwown English logo.

▲ The Misfit Flash bracelet is not only for wrist wear, but also for necklace, metal wrist strap, rubber material, random accessories and clasps, which can be worn in many places. The wrist strap is made of rubber, while the body round buckle is made of PC, which has higher hardness and is not easy to fall off when combined with the body.

『 Hardware ⊙ Wearing 』

▲ The bracelet should be worn closely for a long time. In this part, I mainly introduce my personal wearing experience. The experience after wearing is that the Xiaomi bracelet is very light. Although the Xiaomi wrist has a certain thickness, it is quite comfortable as long as it is not worn too tightly. The BONG2 bracelet is the lightest and most invisible. However, if the arm sweats during exercise, BONG2 will feel less comfortable. Sweat and wrist strap will stick to the wrist, making it uncomfortable. The inner side of the i5plus bracelet is also slightly frosted, and the touch with the skin is also good, but the thickness is thick. When the hand is flat on the table, the wrist will have a foreign body feeling. When moving, as long as it is not worn too tightly, the feeling is still comfortable, and the adhesion is weak. The wrist strap of the Misfit Flash bracelet is smooth and thin. It is usually comfortable to wear, but when sweating during exercise, it will stick to the skin with sweat and feel uncomfortable.

As far as I am concerned, the most comfortable thing to wear normally is the Misfit Flash bracelet, because its wrist strap is light and thin, and its texture is relatively soft. The most comfortable is the i5plus bracelet, because it uses a frosted wrist strap, which will not stick to the skin when sweating.

▲ The Misfit Flash bracelet can also be worn in other ways, such as buttoned in the pants pocket. If you don't wear Misfit Flash as a bracelet, the most comfortable way is to clip it. It doesn't touch the skin, and you can clip it wherever you want.

『 Hardware ⊙ Battery 』

▲ The Xiaomi bracelet uses a built-in 41mAh polymer battery, which can be used after being fully charged once 30 days, use the special charger delivered with the machine for charging.

▲ BONG2 bracelet uses a built-in profiled lithium manganese battery. It is said that it can be used for one year, and the battery is officially available. A battery costs 9 yuan.

▲ The 75mAh polymer battery of the i5plus bracelet has a screen, so the battery life is only 4-5 days. You can use the USB plug on the bracelet for charging.

▲ The Misfit Flash bracelet uses a 3V button type battery. It is said that the battery life can be 6 months, and the button battery is relatively easy to purchase.

In general, although the BONG2 and Misfit Flash bracelets cannot be charged, they have a relatively long life. The BONG2 battery is available on the official website, but it is not as easy as the button battery. The Xiaomi bracelet is rechargeable and has a life of up to a month, which is relatively good. The i5plus has only 4-5 days of battery life. Because it has a screen, and has the function of message reminder, the battery life is also satisfactory. However, in the process of use, the i5plus sometimes inadvertently flips the wrist, and the i5plus displays the time. Too sensitive leads to a waste of power. Otherwise, the battery life can be further improved.

『 Software ⊙ APP piece 』

▲ Xiaomi bracelet The APP "Xiaomi Sports" is as simple as its design, without too many complicated designs. When the APP is opened, the APP automatically synchronizes the information in the bracelet without manual operation. The main interface of the APP is about today's activities and sleep. You can view today's activity records in the left sidebar and turn left and right pages to view them. The right sidebar is the system settings, including device information, intelligent alarm clock, personal information and other system functions. However, there are some problems with Xiaomi bracelet: 1. Apple 5S cannot search for Xiaomi bracelet through Bluetooth. I don't know whether it is an individual phenomenon or all Apple 5S cannot search for Xiaomi bracelet. 2. The "millet movement" lacks statistical functions, such as weekly statistics, monthly statistics, annual statistics and other information.

▲ After the BONG2 APP enters the interface, pull down or touch the YES key on BONG2 to synchronize the data. In addition, the activity record of BONG2 APP is more detailed, which is divided according to the time period of each day, so that people can have a clear view of daily exercise and sleep. However, it is unable to intelligently recognize the movement state. The riding state will be recognized as the walking state, and the removal state is often confused with the sleep state. BONG2 APP has an interactive function. It can PK other people and find friends with high affinity, but these can only be used for entertainment. BONG2 APP also has expansion functions that other APP does not have. It can add other modules to analyze sleep quality, exercise data, and statistics of daily heat consumption and other data. In addition, BONG2 APP can also set up wake up reminder and other functions, and can also connect with WeChat sports ranking data, which is convenient and fast. BONG2 can also record the movement track, but it needs to be used together with the mobile phone. It cannot be used independently. When the movement track is turned on, it consumes more power.

▲ The main body of the i5plus bracelet app is blue and orange, which are bright colors. After entering the APP, if the mobile phone has been connected to the APP, the APP will automatically synchronize the activity records in the bracelet. The left sidebar of the APP is the system settings, which can manage the i5plus bracelet and the APP in the mobile phone pushed by messages. On the right side of the APP is the management of friends and their messages. This function is not seen in other APPs. It should be regarded as the first of i5plus. The i5plus bracelet app has more detailed statistical functions, which can make statistics on weekly and monthly steps, calorie consumption, exercise duration, and exercise distance. I5plus cannot identify the riding status, but it can manually open the riding, running and walking status through the movement status, and record the corresponding activity track.

▲ The main color of the app of the Misfit Flash bracelet is red, which echoes the bright red color of the bracelet. Misfit Flash's APP is shared with other Misfit products. The APP synchronization needs to slide to the left. While synchronizing the activity record, the LED beads on the Flash dial will turn on clockwise. APP has rich functions, including ranking settings, device management, personal settings, etc. It can add notes and act as a notepad.

『 Software ⊙ test 』

▲ After three measurements, the measured results, millet The calculation steps of BONG2 bracelet and i5plus are relatively accurate, but we don't know why the result of Misfit Flash can't be obtained. The result of each measurement is 0.

『 summary 』

To sum up, I think i5plus is a bracelet with high cost performance. First of all, it is not only a bracelet, but also can watch time and touch, which is equivalent to a watch. Secondly, its measurement data is also more accurate. Although it is unable to identify the cycling, it is also a good choice to manually open the cycling track. In addition, i5plus has WeChat, QQ and other message alerts, which are not available in other bracelets. If you want to choose a low price without too much demand for other functions, millet bracelet is the first choice. First of all, the price is only 69 yuan. The price in the bracelet is quite low, and its step data is also quite accurate. The workmanship of the BONG2 bracelet is slightly lacking. The metal surface is not polished carefully enough, leading to prominent edges and corners. Its function is similar to that of the Xiaomi bracelet. Although the battery can stand by for one year, it still needs to buy batteries after one year, which is also an expense. The price of Misfit Flash bracelet is $50 in foreign countries. Maybe $50 is not expensive in foreign countries, but it will cost 199 yuan when converted to RMB. The lowest cost performance ratio is the lowest. I don't know whether the problem is the use of the bracelet or the problem of the bracelet. I can't display the step counting record when measuring. If it can be used normally, the multi wearing mode of Misfit Flash is also a good choice. It can be worn anywhere on the body.
