Scam Signed up to try the whitening gel and then asked to cancel until I was given adequate time to try (as it took three weeks to receive and then another batch would have shipped before I even received the product to try). Cannot cancel subscription - says to email which I've done many times. No response in 3+ weeks.

Great product, HORRIBLE service I got inspired to buy an electric toothbrush from Dintle by someone else. The website offered it for $49.95 plus free 2-day shipping. Unfortunately, I had to email the company because I thought it would never arrive. Nobody replied after several attempts. I even called the phone number listed on the website, but it was invalid. While I called my bank and reported the transaction as a fraud, the toothbrush unexpectedly arrived a month later. Ironically, I actually like it - it cleans well, comes with a travel case, and is lightweight. However, Dintle doesn't sell any replacement heads yet, so this toothbrush will probably last only 6 months. Still, I wish I saw the other negative reviews before spending any money. Please research any unfamiliar companies like Dintle before deciding!

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.

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.

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!!!
