Packaging and appearance

The first feeling when I got the product was that it was simple and crude. The package was too rough. It was only made of two transparent upper and lower plastic shells. It also needed to be pasted with tape to close. There was no detailed instructions, no after-sales maintenance card, and no certificate of conformity. No matter whether the product is good or bad, just look at the packaging, and the sense of quality immediately decreases.

The bracelet is surrounded by a small card inside. The front of the card briefly introduces the product name and functional features.

The back is a full English version of the operation introduction, which is too concise. It is difficult to get started after a few words.
