we have some twirl the top and stick on the wall odor disposers that we buy from any dollar store and they work well for our house. we have them to help our noses because a couple of my babies smell so bad after they go. these are definitely a very nice plus to your house even if you don't have litter boxes or that. they are just nice to have around.

Pros: great smell

Cons: n/a

We use these at the shelter all the time. They help keep the smell at bay, but don't help completly because of the large space. They would work better in a smaller space like a laundry room or bathroom.

Pros: Helps disguise unpleasant odors

Cons: Not good for large spaces

I use these in the bathroom and around the lhouse for other oders like the trash cans,laundryroometc. They work well and are inexspensive.

Pros: Inexspensive and work great

Cons: none

This works well and I would like it to last longer but it is inexpensive and i have animals so my best bet is too just buy more.

Pros: Works well

Cons: would like it to last longer

These are very effective. Recommened to a friend and she bought some. She's very pleased with how long they really last.

Pros: Long lasting

Cons: none
