I work in a factory where wrist watches are not allowed. For the price, the quality is good. But, I worry it's life will be cut short by the harsh environment I use it in everyday. Although, I wouldn't hesitate to purchase this if your environment is less harsh.
The face flipping around is nice, allows for reading the watch right when clipped on your belt loop upside down.

The plastic quality and overall watch/clip construction are good, considering the relatively low price tag. The screw on back claims to be "water resistant" but I doubt it would survive an extended submersion. Biggest negative...the buttons are WAY too hard to push down.

The alarm is loud though, and the indiglo type back-light is bright.

For $20 it is not a bad purchase.
