Bought these for Christmas gifts, for stocking stuffers actually. Forgot where I put them and missed Christmas. When I found them again I decided to keep one and save the rest for next year. After slapping on the watch and wearing comfortably for a day, I plan on keeping them all for myself. I can wear a different watch to match any outfit. They fit perfectly and the silicone strap (I think) prevents slipping around the wrist. These stay where you slap them.

I only give this lot of ten 4 stars since the battery was DOA (dead on arrival) on at least two of the watches. I can remove the watch face from one slappy strap, tho, and put in a working watch face. I assume I can change the battery but haven't tried this yet.

For the money, these watches are worth buying and are great fun to wear.
