Good but difficult to move around/carry
This is a marvel, a fantastic invention! I have 3 cats, and 4 litter boxes. So I need to move the litter locker around the house as I clean out the boxes each day. That is when the litter locker fails for me - as it has no handles! It is very cumbersome to carry and if you don't carry it correctly it can fall open and leave a stink! This is a great product if you are just going to have it standing next to the litter tray and not move it until you empty it (the bags inside are easy enough to carry).
Litter Locker inventors please please please invent a litter locker 3 with handles!!! :-D
