Customer Reviews
Good value, minor issue
I bought the Professional Strength Whitening Gel and some Replacement Mouth Trays. The gel works really well, I noticed my teeth were whiter after about a week of consistent use. The price was competitive compared to other brands I looked at, which was a big plus. Shipping took about a week to get to me in Texas, which was a bit longer than I hoped, but not a deal-breaker. My only small criticism is that one of the replacement trays seemed a tiny bit off in shape, but I made it work. Overall, a solid product for the money.
Worked as expected
Got the Teeth Whitening Pen. Easy to use. Saw results after a few days. Shipping was quick. No complaints.
Great kit, fast delivery!
I ordered the Teeth Whitening Kit and it got to my door in just 3 days! I used it a few times already and I'm really seeing a difference. My teeth feel brighter and no sensitivity issues at all, which is great because I usually have trouble with that. I'm so happy with this purchase and will definitely be buying the gel refills when I need them. I told my sister about it already!

Quick question about shipping, how long does it usually take for a kit to arrive in, say, Chicago? Trying to figure out if I can get it before a trip next month.
Hey, thinking about grabbing a kit. Does anyone know if GLI GLI is actually legit? Like, is it safe to use or just another one of those trendy things that don't work?
