With the development of modern technology, smart products have become an indispensable part of our daily life, such as smart phones Smart TV Smart products such as smart rice cookers have become essential products for families! In recent years, the rapid popularity of intelligent wear has made many electronic product businesses look for business opportunities to join the market of producing intelligent bracelets! There are many brands of smart bracelets on the market. How to choose an economical and practical smart bracelet? Next, let me introduce a new CoBand K4 smart bracelet launched by Demon Lover!

No fancy packaging, just a simple square box! The upper left corner of the front of the box is pasted with Love to play computer games The logo of "Smart Band" is written below! On the back of the box is the device type of the bracelet, display screen, battery capacity, battery type, input voltage, input current, and the color of the bracelet! The introductions are both in Chinese and English, which has a great momentum of going abroad to the world! Open the box to see the host of the bracelet. Below the host is the TPU wrist strap, charging cable and instructions! Demon Lover CoBandK4 The mainframe is oval, which is more aesthetic than those square ones. The 0.86-inch display screen makes it easier for us to watch. The blue font design can clearly see the time even outdoors, and there is no need to look at the time in front of your watch! There is a small sensor on the back of the host to test the heart rate. The design of the wrist strap is TPU skin friendly plastic material, which is not very soft to the touch. If it is a little softer, it may be more comfortable to wear! There are five colors to choose from, namely black, white, blue, yellow and orange, to meet everyone's preference as much as possible! This time I got my favorite black, simple and generous! In addition, the weight of the whole machine is only 17.7g. It is very light to wear on your hands, so you don't have to worry about the pressure when running! One end of the charging line is our common USB interface. I believe that every family has several chargers that match it, so charging is more convenient. The other end is a connector that matches the host. Just connect the host and the charging line to charge! The extra long standby time of CoBandK4 is also a highlight. The standby time is 50 days long, and the normal use time is about 10 days, avoiding the trouble of frequent charging! An excellent Smart bracelet, mobile APP is indispensable! Scan the QR code or download and install apps in major app stores, open the mobile app, search for devices, pull down the scanning device, click the device connection, and the bracelet will automatically synchronize the time after the connection between the bracelet app and the bracelet is successful.

Open my device, you can see the power display and various functions of the bracelet, and set according to your own needs!

The reminder function is my favorite of all the functions of CoBandK4, because now our mobile phones are all large screen phones and it is inconvenient to put them in your pocket, so you can only put them in your bag, so when there are many people outside, you will often miss calls or WeChat. With CoBandK4, it is no longer a problem!

When connected, the bracelet will vibrate and display the name or phone number of the incoming call when the incoming call reminder and SMS reminder are enabled.

APP notification reminder:

After WeChat reminder and QQ reminder are enabled, when WeChat message or QQ message arrives, the bracelet will vibrate and display WeChat or QQ icon and content reminder!

APP notification reminders can also add more notification applications. Users can add according to their own needs:

The dynamic heart rate monitoring of Demon Lover CoBandK4 can better manage sports health!

I tried many times but failed to change the screen rest time. I hope it can be improved! Kilometers, calories, steps and other data can be seen at a glance on the APP home page!

I don't know if anyone will always lose everything like me. What if I can't find the bracelet? It doesn't matter that the Find bracelet function in the APP can help you find it. Click to find the bracelet. The bracelet will vibrate automatically and find it easily!
