▼ The appearance design of the product packaging box seems simple, but it is very careful. As long as the outer box is lifted by hand, the inner box will automatically slide out slowly, indicating that the damping between the inner and outer boxes of the packaging box is well controlled.

▼ The Lexin mambo watch uses a square dial with rounded corners, which is very natural and smooth at the connection of the strap. The watchband adopts the common ring buckle design. In order to prevent the iron ring from being oxidized, a layer of plastic film is specially added to wrap it.

▼ It's time to tear the film. The whole dial is made of plastic material treated by mirror process, and the whole dial is made of plastic material treated by mirror process. The reflective effect is very good under light, but the wear resistance is general, which is easy to generate scratches and collect fingerprints. The front is a 1-inch OLED black and white screen.

▼ The watchband adopts the same buttonhole wearing design as the watch, and the silicone material TPU medical grade material. The actual wearing effect is comfortable, and the 30g weight does not feel particularly burdensome.

▼ Heart rate sensor can be seen on the back of the fuselage. Lexin uses Silicon Labs sensor from Texas. Its four biggest characteristics are ultra-low power consumption, free algorithm, simple structure and dynamic heart rate monitoring. It is also the most ideal sensor for intelligent wearable devices. The plugs at both ends of the body are provided with grooves, which can be stuck in the strap after being inserted, so as to ensure that the dial and strap are not easily separated; However, looseness may occur after long use. The size of the socket of the watch strap is different, corresponding to the size of the plugs at both ends of the body, so that there will be no wrong insertion.

▼ Insert USB for charging, and start using when the screen is lit. This design is very convenient for charging. After the power is used up, it can be fully charged in about 2 hours.

[Main function experience]

1. Step counting and running

The function of counting steps and running is the core function of the Le Xin sports watch mambo watch.

▼ Steps, calories and distance will be directly displayed on the screen of the watch, and daily walking data will also be displayed after data synchronization on the mobile phone. Clicking the corresponding date will also display the detailed walking data of the day, including steps, calories, distance, walking time and steps in each time period.

▼ The running function needs to be manually opened on the watch. After running, you can directly view relevant data on the watch, including steps, calories, average heart rate report and heart rate interval report.

In addition, in order to verify the accuracy of step counting and running, I did an experiment. I actually walked 100 steps, and the step counting deviation was within ± 1 step. I actually walked 300 steps, and the step counting deviation was within ± 2 steps. I actually walked 500 steps, and the step counting deviation was within ± 4 steps. That is to say, the step counting deviation was not more than 1%. Running was also a similar result. This shows that the accuracy of the Mambo watch is quite high.

2. Heart rate

Lexin sports watch mambo watch adopts the Silicon Labs sensor in Texas of the United States. The sensor adopts the green light photoelectric measurement method to measure the heart rate, and the heart rate monitoring is very accurate. The green light photoelectric measurement method is composed of two green wavelength light-emitting LEDs and a photosensitive sensor, which is located at the back of the heart rate meter. The principle is based on the change of light transmittance caused by the density change of blood in the arm blood vessels when pulsating. Light emitting LED It emits light waves of green wavelength, and the photosensitive sensor can receive the reflected light from the arm skin and sense the change of light field intensity and convert it into heart rate. The green light photoelectric heart rate measurement completely discards the heart rate chest band, and can continuously measure the heart rate, calculate the average heart rate, record the maximum heart rate, and set the heart rate alarm interval.

▼ The Le Heart Sports Watch mambo watch is a real-time heart rate monitoring all day long. The heart rate data can be viewed directly on the watch or on the mobile phone. The mobile phone will display the daily heart rate data. Click to enter the heart rate record of a day, and the detailed heart rate data will be displayed, including the resting heart rate data and the heart rate data of each time period.

[Wearing experience]

As the weight of the Lexin sports watch mambo watch is only 30g, the TPU grade wrist strap is not only safe, but also comfortable to wear. However, it is easy to sweat when it is hot in summer.

▼ The equipped 1-inch 96 * 96 pixel OLED black and white display screen can clearly see the content displayed on the screen indoors and outdoors, but in the case of strong direct sunlight, the content displayed on the screen cannot be seen clearly.

▶ About wrist lifting and turning the screen

In order to give consideration to the endurance of smart watches and facilitate the viewing of watch display content, most smart watches and bracelets have the function of raising the wrist to illuminate the screen. The wrist raising and illuminating screen of the Le Xin sports watch mambo watch can accurately identify the wearer's watch watching action, which is very sensitive. This must be praised, but the screen lighting time is slightly delayed.

▲ Due to the number of frames, the GIF picture seems to turn the wrist quickly and display quickly, but the actual situation is the normal speed of turning the wrist and the slightly delayed light screen.

▶ About IP67 protection

IP67 refers to the protection security level. IP is Ingress Protection Rating (or International Protection Code), which defines the protection capability of an interface against liquid and solid particles. The IP is followed by two digits. The first is the solid state protection level, ranging from 0 to 6, representing the protection from large particles of foreign matter to dust; The second is the liquid protection level, ranging from 0 to 8, representing the protection from vertical water drops to the bottom pressure. The larger the number, the stronger the ability.

IP67 explains that dust confinement: dust cannot enter the entire diameter of the object and cannot exceed the gap of the shell; Short time immersion prevention: under normal temperature and pressure, when the shell is temporarily immersed in 1M deep water, it will not cause harmful effects.

Therefore, although the Le Xin sports watch mambo watch supports a certain level of safety protection, there is still a certain limit to liquid protection. It is no problem to wash your hands and get wet at ordinary times, but it is better to take it off when bathing and swimming to prevent liquid from entering and damaging the original watch. Use and cherish!
