3D Caffeine Molecule LED Keychain is a big let-down.

This product has to be one of the worst built that I’ve ever purchased from ThinkGeek.com. Usually, they’re great at providing excellent products, but with this, they really let me down.

I had purchased two of these little gadgets. One for me, and one for my girlfriend. At first I loved it, especially since I’m a huge caffeine fanatic. It came in a small box with the batteries pre-installed. When you press down on a button on the side, the three-dimensional etched molecule lit up in bright blue brilliance. The keychain itself seemed to be well built.

One problem, after two days of using it, the keychain broke. I was of course, disappointed, but at least my girlfriend’s was still functional. Well, at least for the time-being. Shortly after, perhaps a week or two, her 3D Caffeine Molecule LED Keychain broke as well, in the exact same fashion.

There seems to be a problem with it when you remove the batteries from it, because it was at that point that neither of us could get it to turn back on.

But hey, at least it still looks cool. Don’t buy this product unless you don’t mind having it break on you. Or unless you don’t mind ever removing the batteries.
