Worked great initially but did not last as long as advertised. After 3 months of use, there was a slight odor. There are other options and I chose Phresh because I felt it lasted longer and was more thorough at removing odors. I'll try other brands and see what happens. I also emailed Phresh through their website to make sure I received a genuine Revain product and I never received a response. What kind of company completely ignores customer questions?
