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! 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.

NO WAY TO CANCEL SUBSCRIPTION The product works well enough but the customer service is non-existent. The bigger problem is that there is NO WAY TO CANCEL YOUR SUBSCRIPTION. The only way you can cancel is to email them asking to cancel but they never respond. I emailed 3 times in a month and a half and never was responded to and there’s no phone number to call. The only way I could cancel was to put a different card on file and cancel that so that I wouldn’t continue to get charged. This is either an unethical company or incompetent either way STAY AWAY!

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.

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