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.

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.

Scam! Doesn't work. Will charge you and ignore you I tried to cancel numerous times because the whitening pen does nothing but make my teeth sensitive to cold and pain. Eventually my account was cancelled, but not before I was charged $34.95. My requests for refund have all been ignored. They have actually never responded to any emails and that is the only method they have to contact them. I believe they are a scam because their is no way to contact them and their product doesn't work.

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!

Happy bright smile customer I have use the product for 3 days and I already see results my teeth are looking whiter. I do have to contact them about the mouth piece and they respond right the way and help me with issue. I can’t wait to keep using it to see the results and by the way I haven’t feel any sensitivity like I had before with other whitening treatments. Thank you for this product and I will recomendé to every one who wants to bright there smiles😃
