A friend and I both got one of these for Christmas and they look great. Its the first day back at work and both have leaked. On mine the plug went at the bottom after only minimal use, shooting red gel all over my work. Not Happy, avoid! Its a stress ball that you can't squeeze or it ends up causing you more stress.

At first i was expecting an oange balloon filled with flour type material. I was surprised to find a strong rubber ball filled with a gel liquid. It doesnt look like the picture the 'ears' are alot smaller and the ball itself is about 2.5 inches high/wide.
Nice and squishy but its so full, i'm scared the 'plug' on the bottom might come out when i squeeze it. Don't know why i'm worrying, its a stress ball for pete's sake. :) I'd recomend it, even if your not stressed.
