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.

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😃

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.

It’s company is a scam It’s company is a scam. Please do not buy their products!!

Canadian buyers beware!!! Canadian buyers beware!!! Dintle offers a 30 Hassle Free return policy. After reading the fine print.... only valid if product is unopened. How do you try a product without opening the packaging? Also they charge shipping to Canada but when the product is delivered, you have to pay an additional fee for duty and taxes. Save your money people and buy from a legitimate Canadian company.
