The quality of Mi bands is extremely wonderful, there is nothing new to say about this band. Among thousands of cheap smart watches in the market, this smart watch is for those who look for a bit of quality.
It is 100% waterproof. I have even bathed in salty sea water wearing this, nothing happened.
Its condition is like new. No scratches, no dents.
You can check it as much as you want. You can dip it in water as much as you like before buying, if there is any problem I will not take the money.
100% original and 100% quality product.
You can learn more details from YouTube if you want.
