Thee best product I've ever used!!
I have used many different 'supposedly' teeth whitening strips, pastes, gadgets and never had a result, so I was a bit reluctant to try Smile Science, I read reviews on various different platforms and they were all positive so I took the plunge and let me tell you I am not disappointed in any way, after only day 3 of using the LED light activated kit I have seen a big difference, at least 2 to 3 shades, it's a 10 day treatment process and says it can whiten your teeth upto 8 shades whiter! So, so far so good, I can't wait to see the finished result!! I most certainly recommend Smile Science Harley Street Professional Teeth Whitening Kit LED Light Activated (for sensitive teeth). The kit I got has a pre-stain remover liquid and brush that makes my teeth and mouth feel so ready for the lightning process, it has a really nice minty tastes, leaves no nasty aftertaste, 2 x 5ml syringes pre-filled with whitening agent gel, 2 x syringe tips for a precise application and to stop you from squeezing too much gel out and wasting it, 1 x LED plasma light, 1 x integrated mouth tray, 1 x 7ml pre-stain remover. 
It's so easy and fuss free to use, just 15 to 20 minutes and you're all done. The mouth tray can be detached easily for cleaning, comes with batteries so no having to charge before each use.
Massive thumbs up from me!! Thank you Smile Science for giving me the confidence to smile big again!!
