Super speedy delivery from the US to… Super speedy delivery from the US to the UK - my order literally took a few days. The price is a fraction (a tiny fraction !) of what the identical product would have cost me direct from my dentist. And it works brilliantly ! Thoroughly recommend for service, product and price (I use the 16%) and will be continuing to use Expert Whitening.

45% gels do NOT work at all. Waste of money. Purchased the 45% strength gels, thinking they would definitely work, and they promise to whiten teeth after just 15 minutes, but they have not made my teeth any whiter after several 1 hour sessions. All this gel has done is burnt and irritated my gums and also made my upper lip swell up. Also, the syringes are designed very poorly so that when you take off the cap the hole is too big and too much gel comes out. How hard is it to design decent syringes. Finally, took forever to arrive. Total waste of money, this. Do not buy from them.

order not arrived Ordered from USA around 21st June: it arrived at Heathrow on 25th June. It is now 11th July and tracking shows that it is still in London. I complained 2 days ago but it has still not arrived.

Definitely starting to see a difference… Definitely starting to see a difference in the colour of my teeth.. Have spent the last week perfecting how to apply this product so so carefully so not to allow it to come into contact with the gums as it burns so so badly. I have found that using a mouth guard (from a game of speak out) to open the mouth wide and applying the product to each individual tooth with a tiny brush the best way. Usually have to put cotton wool down the sides to avoid saliva running onto teeth. Works best with uv light and also 1 hour rather than 30 mins. I haven't found sensitivity a problem. Hope this review helps someone.

works well 😎 Good stuff better than all the other **** you see online would recommend i got strongest one 44% gel so dont know about less strong ones but its works great in couple of days 👍 5 stars ⭐️ ⭐️⭐️⭐️⭐️😎😬
