I give it a 5 star
I have  tried several other brands that was awful tasting and didn’t give me the whiting quality that this one does, I’m happy with my purchase and will by more again when I’m out, if you’re looking for a whitener that is easy to use this one is great instruction is easy to follow not messy I gave it a 5 star  I even got one for my grand daughter and she love it too she’s happy with her results as well her teeth was dull now they are much brighter since she’s been using it It really does Whiten your teeth I’m happy  and she’s with it.
