Excellent
Even though I checked all the reviews and they were all glowing, I still didn’t hold out much hope for this product because I’ve been stung so many times in the past, But it’s bloody brilliant!!!! Since using a whitening system from my Dentist, my teeth now stain so easily (Don’t ever whiten your teeth!) I have to go to the dentist every six months to get them cleaned and now I won’t have to because this thing is excellent! Definitely worth the money highly recommend!!!
