After about a month of wearing it, the strap stretches and one of the clasps goes beyond. Also, after a few pulls to charge the watch, the inner white plastic that essentially holds the mi band got distorted and looked terrible. The original strap is much more durable.

I wanted to get a blue one as a gift and either it's not as it appears in the photo or they sent me a black one. I don't have such a big problem, but the black one was cheaper and I paid a little extra to specifically get the blue one.

If I could give half a star, I would. Unacceptable product, in the 5 days that I took it out to charge it, the strap came off and essentially it is now useless.

It broke the second time I used it for charging. The part around the band stayed on the band.

I don't remember which store I bought it from. I say this because obviously it's a matter of quality and batch in such things. It has happened to me with many items from eBay.
On the third time I put it on - took it off, the plastic that goes into the slot of the band 4 and holds it in place came off the strap. I almost couldn't cut it without damaging the band 4.
In contrast to a gray strap of the same price (which I bought from another store on the same day), which looks better and has withstood many put-ons and take-offs.

It does the job just fine. It seems that it is not authentic and unfortunately it protrudes a little to the left and right of the Mi Band. The color is identical to the original.

Fast shipping and delivery. It is not genuine, but it does its job quite well. I consider some lines from the rubbing on the wrist to be normal.

I have it for about a month. From the beginning, it seemed to be of lower quality than the original, nothing amazing though. It doesn't come off the hand or anything like that, it does its job just fine. Its only problem is that in the areas where it rubs during use (e.g. on the desk, etc.), the color has faded quite a bit.
