Speaking of Jiang Zhishu in Zheng Yuanchang's version of [Kiss of Trick], it is a perfect incarnation. With an IQ of 200, a height of 187cm, and a high face value, everyone aspires to it. The corresponding heroine Yuan Xiangqin is stupid, simple, cute, and full of vitality, just like the CoBand K4 smart bracelet of the Demon Lover. It has powerful functions, not only integrating the functions that all bracelets should have, It is healthy, entertaining and ornamental, and has developed its own unique functions. It also keeps "small and beautiful, professional and refined" for all people. For this bracelet, I really want to use it to bind my favorite people. Because it is you, I want to make it more perfect.

Take a family photo of the magic charmer CoBand K4 smart bracelet. After a few days of running in with the magic charmer's technicians, we fully found that the magic charmer CoBand K4 is not perfect at present, and there will be small problems in the application and APP, but the magic charmer's technicians will answer the problems at the first time, find and solve the problems, optimize the application and APP, It also fully shows the after-sales and technical support of Demon Lover. A good brand should be like this.

I have to say that I feel great after sales.

When we get the Demon Lover CoBand K4, the outer packaging is simple, and the back is only a secondary label. But we don't use the outer packaging when we buy things. It's the hard truth to save costs and use it in actual products.

Open the box and see the Demon Lover CoBand K4 host in the middle. The surface is as smooth as a mirror. I can't help feeling it with my hands.

The box has a second layer. Open the compartment and it is the TPU wrist strap, charging cable and instructions of the CoBand K4.

Here, I want to give a close-up of the instructions of CoBand K4. They are really detailed. The front and back are in Chinese and English.

Through the manual, we fully understood the monitoring principle of the Demon Lover CoBand K4 bracelet.

The TPU wristband of the Demon Lover CoBand K4 not only integrates the texture of skin friendly materials, but also avoids the unique fingerprint and oil collection characteristics of the skin friendly materials, which is very rare. The seemingly insignificant function is a problem that will be troublesome in actual use, but the Demon Lover CoBand K4 has avoided it.

The appearance design of the Demon Lover CoBand K4 is oval, which is not new, but the wrist strap is really smooth, which is much better than most bracelets.

The iMoke CoBand K4 smart bracelet is used with the APP, so scan the QR code to download the APP according to the instructions.

Open the "Demon Lover" APP, register and log in, and fill in the information.

Click the logo of the bracelet in the upper right corner of the "Demon Lover" APP, and you can use Bluetooth to connect the bracelet.

The "Demon Lover" APP can strictly record weight changes and tell you the BMI value.

The "Demon Lover" APP can record sleep, heart rate and pace at a glance in real time to better manage sports health.

The "Demon Lover" app can set its own goals, log in to the leaderboard with the number of steps, supervise your sports, and add friends to each other through the app, sending text, voice, and pictures to run together.

What I like more is the information reminder. The 0.86-inch OLED display screen makes all kinds of data and information clear at a glance. It is very convenient to set up the desired software information reminder, and my mother no longer has to worry about me missing her WeChat message. At the same time, the interface display can be switched between horizontal and vertical screens to meet different user habits.

The CoBand K4 bracelet of Demon Lover is not perfect in the bracelet and APP, but I like the brand of Demon Lover very much because of the powerful, serious and active after-sales and technical personnel. In use, the CoBand K4 wristband of Demon Lover avoids the fingerprint of skin friendly materials, the oil stain collection characteristics, the sensitive screen, the overall weight of 17.7g, and the burden free wear are all attractive features.
