Okay, so I finally caved and tried these after seeing them EVERYWHERE on social media. Here's my real talk review after using multiple boxes.

First off - the sensitivity thing is legit. My teeth usually hate whitening products but these didn't cause any pain at all. Major win for us sensitive-tooth folks!

The whitening works...but slooowly. Like snail pace compared to other brands. I'm talking 3 boxes in before seeing decent results. If you're in a hurry for a wedding or something, maybe look elsewhere.

Application is kinda annoying though? You have to dry your teeth completely and they still slide around like they're trying to escape your mouth. And that weird gel residue after - ew! It's like someone melted marshmallows on your teeth.

Would I buy again? Maybe if I found them on sale and had patience. They do work eventually and the no-sensitivity thing is awesome, but be ready for some weird texture issues.
