The first time I used this product was very successful. This second batch is less well made, and the dispensers break far more readily than did the initial design. The waste factor is unacceptably high as a result. I assume the whitening factor is similar, but as the applicators come apart where they shouldn't it is hard to apply the solution.

I am older and my teeth are stained. It did whiten up my teeth after 5 days but they didn’t get that nice white. I will use it again right before the wedding of my daughter. Easy to use and it works.

After i use it, i find it hard to clean it up. It keeps coming out so i'm wasting a lot of product (very expensive product). i've tried many ways to wipe it up, but not finding the right way where it stops coming out.

When I opened the solution to apply to my teeth, the blue part of the tube popped off and would not stay secured to the base. Then had trouble applying because solution would not go thru the blue part, extremely messy. Happened on 4 of the tubes.

It has caused Oral Thrush.
