Love how strong and bright this device is. I have had the cheapies from Amazon and some of the handhelds and they don't compare. This fits nice and snug on my head and I love that I can wear it while walking around doing stuff. I have been doing it daily for a couple of weeks and I'm starting to notice a more balanced complexion. The only downfall to this device is that you have to charge the battery. If you're using the mask for the full 20 minutes at full intensity, it will drain the battery completely. So if you plan to use this two times a day, you definitely have to remember to charge it in between. Thankfully, the battery charges fairly quickly. For this price point, I would like to see a larger battery that can last a couple days at least.
