COLGATEMax White Ultimate at Home LED Teeth whitening kit | Enamel Safe | Reverses up to 20 Years of Stains** | Whitening Pen & Smartphone Powered LED Whitening Light | Developed by Dental Experts

I used as directed (morning and night) for 2 weeks, but surprisingly started to see differences after just a few days, by the end of the 2 weeks, my teeth are DEFINITELY brighter.As a guy who drinks a LOT of coffee and was a former smoker, I was sceptical about how well this would work at first but, the price was reasonable so, I thought, why not give it a shot.I used this combined with the "max white ultimate" toothpaste for brushing and the results have been surprisingly good and fast as well.Didn't expect to be giving this 5 stars but, it definitely earns them and would recommend to anybody.Only thing I'd say is just make the cable a bit longer. As a guy over 6ft, it would make things a little easier.

I've tried the product, and whilst it will whiten the teeth a little bit, 2.5ml is useless.Its not enough given the price of the product. Its too easy for the pen to dry up, and why is it even a pen used ? Well to hide the quantity, that is why.Not worth buying. Its a con, and I would expect a manufacturer with such a name to do better for customers. Clicking a pen, to release a drop of product, its a con. The pen should be filled, what you'll get inside, is a spring applicator and a piece of plastic that dispenses a tiny drop of liquid through a tiny tube.You are paying for an overpriced light source, gum shield, and plastic pen design.Sad to say, Colgate you have failed with this product.

I tried the Colgate toothpaste at £8, didn’t work. I then tried this which didn’t work. Need to stop wasting time with these kind of products and get down to a cosmetic dentist.

Quite shocked to say it's actually worked!Teeth deffinately whiter...good job as its quite expensive...have told everyone about it and had 2 comments on the whiteness of my teeth!. Ex-smoker....yeah,...works and I'm happy!

Very good

It seems okay so far.It easy to use and for me, it seems to be working, I use it along with the blue coloured stain removal toothpaste.It seems to remove tea and coffee stains.I don't smoke, so can't say on those stains.

After reading instructions, it wasn't forme.

Ok but not as amazing as as they make it out to
