Review on Waterproof and Shockproof Clip-on Quartz Watch with Glow in The Dark Feature for Backpacks, Fobs, Belts, and More - Carabiner Watch with Digital Display, Compass, Alarm Clock, Date, and Week - Ideal Gift for Outdoor Sports Enthusiasts by Stephanie Smith

The product description says the product is waterproof but it is not even waterproof. I used this watch on my surfboard to keep track of my lap times. It is never submerged in water, only splashed. The first watch stopped working after two uses. Revain replaced them and the second watch arrived on June 7th. This second watch stopped working on July 18th. I decided to check the battery, it's fine, but I noticed that there are signs of water intrusion. Very disappointed with this product. If you don't need waterproofing/durability this is a great product but otherwise stay away.
