I was a little hesitant, but I'm pleasantly surprised! No sensitivity at all, easy to apply, and I noticed a huge difference in my smile after only the first 4 days. These are definitely gummy and leave quite a bit of the product on your teeth when you take them off, but honestly so easy to remove after rinsing and brushing with water. These also leave a few white spots on my teeth, but typically disappear within a couple hours.
