    I got some of these from America last year, the exact same ones, (well they look the same anyway), they didn't do any good, unless of course we didn't use them right :(.

    I see some beauty salons are doing it now, it might be worthwhile checking them out instead.

    33% and even 22% is way too high. 10% is the gold standard for various reasons. also the trays need to be professionally made ,with high accuracy impression materials that develop the bit of the tooth next to the gum. the casts also need spacers for the material on the outer surfaces. doing it another way wont work too good. also it should be done under care of a dentist as there are one or two problems that bleaching actually makes worse (little white spots that appear far whiter)
    hope that helps.
    edit/ apologies just looked at the ebay item again the 22% or 35% is for short time use. however these can burn the gums. no dentist would use that strength would gingival protection something you cannot do with a diy kit.
