8 Jun 2021 Good afternoon sorry to hear you are not happy with your device. Unfortunately, this device does not offer a money-back guarantee. As you have opened and used the device, we are unable to accept this device returned." Gabriela CurrentBody I typed: of course "I opened the box and tried the product". I am not satisfied and requested a refund not even a week after receiving the mask. So, basically you are saying you don't stand behind your products? User's recommendation: Do NOT use them... I wish I would have read the reviews prior to ordering from such a cheap company. The mask is just a piece of rubbery plastic held together with velcro (That pulled my hair the whole time).
