I was very disappointed with Xiaomi, as they do not manufacture spare parts for their products, with the intention of the consumer buying the next one.
So, in order not to throw away my €60 Amazfit smartwatch, whose strap was cut in about a year of use, I bought this one as a replacement.
It is of good quality and secure in the buckle. Obviously, it causes sweating due to the material, but anyone who uses a similar product is probably familiar with it.
After about a month of use, it seems that it may loosen on the wrist, but without losing its elasticity and without bothering/falling off.
Cleaning with a little paper/cotton and alcohol makes it look new.
