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.

Simple, easy, and noticable Simple, affordable and most importantly I notice results! Still going through the first month but my teeth have already changed to a lighter shade. No sensitivity issues either. Excited to see what three months looks like.

I was very excited to receive the tooth… I was very excited to receive the tooth whitening pens, although my teeth are extremely stained and I’m not see a lot of change. I’m sorry I can’t give a better review but I’m certain it’s my teeth and not your product.

Forces you to cancel via email and ignores them Forces you to cancel via email but ignores all emails. You cannot even remove your payment method to avoid the charge. I was just forced to purchase another $35 worth of their product that I did not want. Never responds to any email. Terrible company. Edit: I found this in the order after you pay them for the “free” trial. Free Trials When you purchase a free trial product, you are agreeing to a minimum of 2 billing cycles before cancellation. Cancellation can be made at any time after that period within your account which had been emailed to you. Free trial products do not have a refund period. Absolutely predatory company forcing you to give them money.
