Has anyone used one? It's supposed to have a similar concept as a diaper genie only for cat waste disposal. I got one today to try out since it was only about $10 for the unit and it came with one bag refill. I'm tired of wasting so many grocery bags every time I scoop so I thought I'd see if I like this thing. I'll let you guys know what I think http://slashpaw.com/2010/12/18/angelcare-litter-locker-ii/ Is it odd that I'm actually excited to scoop the box today?
