Overall rating: 4.8 / 5 from 121 reviews.
I've wasted money on cheaper kits before and honestly expected similar. This was completely different, could see the improvement after a few treatments.

The shade guide is actually really useful because I didn’t realise how much they'd changed until I compared them.

Good kit. I would have liked slightly clearer instructions around how much product to apply initially but once I figured that out it was easy.

Had a few people ask if I’d had them professionally whitened which says it all really!
