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.

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.

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.

Going to Starbucks is always giving you… Going to Starbucks is always giving you that feeling of cozy and relaxation, you almost feel like being in a piece of a movie, almost like the Friends famous bar (@CentralPerk), with the chatting, people working, the smell of coffee, and the ultimate trend in the air! And they always have special beverages to try... I love it!!

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😃
