“ My only remark is to follow the directions, on one of the papers inside you have a link to their website and they have a step by step video on how to prepare and use it!i would highly recommend this product and seller!thank you i've used whitening strips for years but this is much much better ”

“ I saw results in the first treatment, the shipment was extremely fast and everything was perfectly packed!the light is working without any problems,its strong and durable ”
