Want return product Want return product, not working

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.

They never sent my order They never sent my order. I also emailed two different email addresses I found for contacting them, and the emails bounced back. I ended up having to get my bank involved to get my money back.

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😃

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!
