I can't speak to the product's effectiveness because I am hung up on the stupid glue they use to stick the two bottles together just so the package is pretty. It is UNGODLY hard to get off of the bottles. Its so tough that after using a pry bar to get the bottles apart, the remaining residue will stick the bottle to my hand or really any other surface I place it on. Took a lot of elbow grease and two different solvents to finally get rid of it. Ridiculous.

Cleans well, has an exceptional strong unpleasant odor

I needed to purchase since you don't refill bottles anymore

Not Good
