Convenient and easy to use Whitening Device. I drink a lot of coffee and had pretty bad staining on my teeth. This device gave me a whiter smile in just 16 mins!! I also experienced NO sensitivity. Would definitely recommend.
I like how fast and easy it is, it just plugged into my phone and i kept it in for 15 minutes then i'm done! Way more convenient than having to keep the trays or strips or whatever on for hours just to get the same results
