...I have quite a few friends who have their own tales of woe with PebbleTech. How this company stays in business selling this crap is an enigma. You'd be better off just digging a hole, pushing rocks into the dirt, and filling the thing with water.

Oh... and if anyone's interested, I have some nice large chucks of PebbleTech for sale. Cheap. You can use 'em for paperweights (before they fall apart into smaller pieces, that is).
