I like the fact that you can use this product on any inflamed spots without having to use a full mask and protective eye glasses. This means that you can use it while watching TV, etc. and it will beep when the 20 minutes is up. The blue light helps to kill the bacteria responsible for the spot. I would not use it for blackheads or whiteheads though. It helps to reduce the swelling associated with inflamed spots and helps to speed up the healing process. However, the stickers to attach the device to the face can leave a little residue on the face but one can easily wipe it off afterwards. Also, it is quite heavy if placing it near the edges of the face. So I tend to hold it when it is placed near my chin to prevent it pulling on my skin. Overall, I would recommend it for people who get red, inflamed spots to help clear them up quicker and who did not want to use a full LED mask.
