Love this product as it really works, easy to use and you can see the difference from first time using and no sensitive teeth

Just wanted something to lift light staining on my front upper and lower prior to going to a wedding .....as I knew there would be quite a few photos taken ....I did the job nicely .....good value 😀🙏

I was disappointed with this teeth whitener. It sounded great, but I haven't noticed any difference in the whiteness of my teeth. I also felt it was expensive given there were only 2 small syringes of whitener.

Used this for a while, though I don’t have a smile like Ryland, I think it keeps the stains at bay

I suffer from mouth sensitivity due to gum disease many many years ago. I shy away from teeth whitening as most of them were reported to hurt if you had any sensitivity - until now.I saw this product on QVC, the TV shopping channel. It was being sold at a special price but more importantly, it had been developed for people who had mouth sensitivity. Upon arrival I was a bit apprehensive but I wanted whiter teeth. I was pleasantly surprised, I did not experience any pain at all and the more I used it the whiter my teeth became. I’m not sure you would achieve that really bright white but certainly you would achieve a few shades whiter and once the shade of white is achieve you only have to use it as a maintenance product. If you initially purchase with QVC they usually have a 60 day return policy, this provides total peace of mind in case it doesn’t work for you. I will keep using this product and obtain my refills from Amazon as its more cost effective

Have been using this product and I am a smoker who drinks coffee and this has lifted the brown/yellow stains.It’s a very easy product to use and doesn’t have an unpleasant taste like someone I have used before.I love how it comes with the whitening chart- will defiantly be buying more.

My fault didn't read it properly, as I haven't got the main stuff I can't use this refill.

Pretty standard teeth whitening product but a little disappointed with the strength of its whitening capabilities; thought it would be more powerful but, on the plus side, it did not cause any sensitivity like other products I have used. 4/5 stars.
