Review on Kids Sand Timers Pack - Hourglass Timer Set 1/3/5/10/15/30 Minutes - Plastic Sand Clocks for Games, Classroom - Mini Hour Glass Sandglass Timer (Pack of 6)... by Jami Harrison

Why should I give 1 star. This "waterproof" timer is defective. The second shower has a timer, it is damp inside and no longer works. Remember, just because it's waterproof doesn't mean it can be submerged in water. This timer is placed on the windowsill in the shower so that it is cleaned by very little water. I will be surprised if they send me another one for free for my troubles.
