It works, I was skeptical but not anymore
It works, I was skeptical but glad I purchased it (June2025) I have left the before and after photos on your Facebook posts too. I am now booked into the dentist to keep my teeth in shape and look at whitening. It has boosted my confidence. I was skeptical and the type of person to say never buy from a Facebook advert. However it has in one use (used it three times since) completely got rid of staining and stubborn plaque on the inside of my bottom teeth. I am stunned at how well it works and recommended to three friends who all were shocked I'd only used it once. Honestly if you buy anything buy this product. Start from the low setting first and build up until you feel comfortable. I use Middle and am happy with my purchase.
