I bought two of these to replace the bands on two of my wife's watches. The first thing I noticed is that they are adequately substantial, but the black surface is very thin. As I installed the bands, the exterior skin cracked with the bending required, showing the white material beneath. Also, the springs that hold the bands to the watch are not high quality. Of the four springs I used, one of them did not re-extend once it was compressed. I will post a pic if Amazon allows this. The non-expanding spring was basically useless, and I had to use the spring that had been on the previous band. For an everyday watch that you don't care too much about its appearance, it's a relatively good value. However, if I were doing this again I would pay a little more and get higher quality.
