Power Bright Teeth Whitening Kit

I drink... a lot... of coffee. No such thing as too much. Sadly, my teeth do show it. I've tried various whiteners over the years with mostly barely a difference. This Power Bright Whitener is still not the miracle I hope to find someday. The system is easy enough to use. I don't like the idea of using my expensive phone to power things. This seems to be an idea that more and more manufacturers are using. I guess it saves the expense of a battery. No matter, I used a usb battery pack instead of my phone and it worked great. The oozey gel is easy to apply to the backside of the mouthpiece and the taste is mostly neutral with a slight hint of peroxide. It's not awful. It's not delicious. It tastes like work. The mouthpiece is soft and comfortable. The wire stays out of the way of my lips. I do with the mouthpiece cable was about one foot longer but, as is, it still does the job just fine. The cable comes with lots of adapters to suit any current usb standard. The results were... not bad. As mentioned, I drink way too much coffee. So any improvement is still a plus. That said, I think this will require many, many applications before it brightens up enough for me to even care to put in the effort. We used the handy included color chart to document things. My teeth have improved approximately "two color notches" over two applications. Again, it's not enough to notice day-to-day but, maybe, over time? Maybe we can knock out four or five color spots. *That* would be noticeable when I smile. Final Verdict: Mostly approved. It does work and does what it says. If your teeth are heavily stained it won't make them instantly pearly white and will take multiple applications on your part. Nevertheless, it works as it is advertised.
