Review on CATLINK Self-Cleaning Cat Litter Box with 1 Bag of Cat Litter - Automatic Cat Litter Box with Double Odor Removal - Ideal for Cats weighing 3.3 to 22 pounds (Young Version) by Malania Yonardy

Installed and forgotten until you empty the recycle bin. Note that the manufacturer suggests that you unplug before emptying the bin (I assume this is to avoid bin-level IR sensor errors). There are many sensors on this device, including a collision sensor, so don't rely on them. Mine came with a panel offset from the front, but that doesn't interfere with normal operation, so I'm not worried about that. Otherwise the fit and finish is good. VERY QUIET. Time affects the total cost.
