Popular for good reason!
All it took were 2 sessions before I noticed a brighter, whiter difference! They stayed on fine for the most part although for some reason the bottom strips wouldn't stick to the backs of my lower incisors as well. Also no issue with discomfort or sensitivity

I've been using them for 10 or more years. They do exactly as promised. Beautiful white teeth.

Meh results
These sort of work….. but are a lot of work for me to use. morning and night. There just is NOT enough bang for my buck and also the whitening power misses BETWEEN my teeth so I feel gel in a tray is the next option or a one time whitening session from my dentist which includes trays and gel for later touching up!
