Arrived yesterday. Looking forward to using it, have to pick up some distilled water to use with it. Thanks O. Brand has been in the healthcare industry for years. Should be a reliable product.
Pretty difficult to use due to the size. You have to keep the whitening product on for about 15 minutes, but by the time is up your jaws will ache horribly form having to hold this in place for so long. I think you could find a better option.
