Good as it gets.

Smells nice, not over powering. Convenient container to store them in. Works great. Nobody likes the sewage chore but this is as good as it gets.

Works as it’s supposed to!

[This review was collected as part of a promotion.] These are great. They are way to use and seem to do their job. We just one in and we are good. The problem is to remember to do it after we dump! This is much easier than the powder and scoop we alerted using before.
