It's not super strong, but it's enough to freshen up the toilet and clear the air around a litterbox post scoop. Some of the drops I've bought in other brands either make my eyes water or have a sickly sweet scent that I end up hating even more than the original smelly smell I didn't want to smell.
This is a nice compromise! I'd buy it again but I'd like it more if there was a larger size option to have around for a while.
