Professional Single LED Light Speeds Up The Process

It did not work after 7 days of.. even i change the battery.. Waste of money..

I spent a lot of time researching teeth whitening products before discovering that hydrogen peroxide is the main ingredient used in all of these teeth whitening kits that we see advertised for $20, $30, sometimes even $50...After brushing my teeth, I rinse my mouth with normal hydrogen peroxide (literally found in any grocery or dollar store) and use the LED light for 10 minutes. I keep up this routine 2-3 times a week, depending on how much coffee/dark liquids I drink.TDLR: Just buy this + some good ole hydrogen peroxide for the fastest and cheapest results.

**Update: After posting my review, the seller reached out to me almost immediately to send me a new blue light free of charge. I'm very happy with the customer service and can't wait to keep using this product as it was the brightest blue light I've bought and so amazing for the price.Used it once and worked great! However, after rinsing it off once, water got into the battery part and immediately rusted and stopped working. I only had it for maybe 12 hours before it broke. Definitely not waterproof like advertised. I would consider buying again however because it was the brightest blue light I've bought!

I bought this because I just needed the LED light. The one from Colgate was way too expensive and I already had crest white strips and the pen. This worked out just great. So far after one use for some reason I see my teeth look slightly lighter, not a huge difference tbh since it's one use. The LED was so simple to use, didnt cause burning or sensitivity to my gums or teeth. Would but again, but my concern was that It didn't come packaged. It came in a zip lock bag and I didn't see the warranty slip for mine. Can someone explain that to me?? I washed it before using as everyone should cause I was very suspicious about why it didn't come in a box like shown. I will continue using it this entire week.

White strips weren’t getting my teeth white enough. With some research I learned about this light. Only 2 strips in with this and my teeth went up like 2 shades. Really happy with the purchase. Much cheaper than the $50 kit. Only use the light for the last ten minutes of the strip ***

I use this in conjunction with my white strips, and my God does it make a difference. GET THIS!!!
