Disappointing
My teeth weren’t that yellow to begin with, so I was hoping they would whiten fairly easily. However after 5 days of consecutive use (even taking photos in the exact same lighting and time every day) I have seen ZERO improvement. The only upside is I didn’t experience any sensitivity like I have with Crest white strips. Flavor is also ok. Having to reapply the gel 4x for one treatment session is also kind of annoying.  Given the price, was hoping for better results.
