I discovered last week, the same shovel and slammed shut. The idea I find great !! However, I find the implementation flawed. I do not use clumping litter of Thomas. The clean chunks are too big for the holes in the tip and can be very bad seven. The container is rather small for the amount of use cat litter (two cats with me) take on. He's very fast. Although the large lumps fall into the container, but fairly easy to get out if you do clean on again.
I hoped it would be little more but not bad compared to a normal litter scoop. And for about 8, -Euro can to try and make his experience itself it quiet.
