Used these a few times and saw no difference whatsoever,for the price normal cheap toothpaste did the same job.

Honestly not worth the time or money didn’t make any difference really 

I found these easy to use and wasn’t expecting drastic changes In all fairness. I’m a coffee drinker so wanted something to take the yellow ness away and these did the job, didn’t make my teeth dazzling white but took away the yellow tinge. Would purchase again but only if on an offer. 

Trays and really small, didn’t cover my teeth properly and didn’t make much difference either :( 

I was sceptical at first but this product has definitely made a difference and I can see my teeth are a few shades whiter
