This company is sketchy. This company is sketchy... once you've signed up for their product you are unable to cancel. There is no way to contact them besides a single email address that seems to lead nowhere. A few of my attempts to contact them have even bounced back! I would caution anybody to avoid Dintle at all costs unless you want a lifetime subscription to their subpar teeth whitening product.

Cancellation not honored I have sent several messages and a screenshot of my cancellation on March 16. You continue to bill me. You have forced me to take this up with the Better Business Bureau. It would seem from the lack of response to any of my emails that customer service does not exist at your company. Extremely disappointing!

Horrible Horrible! I can't cancel my subscription and I've been emailing them daily for weeks... they don't care at all about their customers, not worth reviewing the product because this is a scam.

More than pleased I tried this the first time with some hesitation. Never trust your inner thoughts. Although the only matter at hand was not being able to obtain another order as quickly as I'd expected, overall I'm completely satisfied.

My sensitive teeth don’t hurt!!! YEEEES Been using Dintle Bright for a week now and I’ve been loving it! I have CRAZY sensitive teeth and was really nervous about the claims of “zero sensitivity.” But really… I’ve had no sensitivity reactions from it. WHAT A RELIEF. This was my main concern with my other tooth whitening experiences, and if the positive results keep going the way they have, I may have just found my perfect solution. YAY!!!
