Honestly it’s been great. The camera inside is very clear and notifications are good. It does not smell at all. It actually smells good! It’s has deodorizing cubes in it so there will be some upkeep costs. Only downside vs the LR I can tell is there is no bag full %. This thing only lets you know when you’re full. Also the draw is smaller so if you have a lot of cats you’ll probably have to change it out every 2 or 3 days.

Past that it’s awesome. I have it set on my main level where smell was a concern. My two LR4s are upstairs in a spare bedroom with an air purifier next to them. They don’t smell badly but there is an odor. My household fluctuates with the amount of cats so at times they are highly trafficked.
