pricey but worth it

i love to bleach my teeth, and be warned when i say this, i have zero sensitivity so im not one to ask. this doesnt lighten much, tho, maybe im too light already to see a diff and it maxed out, but for the awkward tray and the pain in the rear holding...

I was all excited when I bought this, I was expecting great results. What I got was maybe 3 shades whiter than before the treatment. Nothing special, especially for the $$$.

I wasn't pleased with this product at all. I found it to be uncomfortable and an unpleasant experience in every way. On top of it all I noticed no difference. I'll stick to the good ol' strips anytime!
