I love this tool! I love how versatile all the colors are; most only have 3-4 different colors to cycle through, but this one has 5! I usually use mine while I watch TV after I finish my face care routine for the night, it leaves your face feeling so smooth a few days afterward! My face is very acne-prone, so I try to use the cyan blue light and the light green on my face to help reduce and treat blemishes. I have only used it a few times so far, but I am loving the results. While the device design may look a little complicated at first, I promise the instructions are very easy to read and follow. Just make sure that you clean it off after each use with rubbing alcohol or disinfectant wipes so that you do not transfer leftover oil during your next use! For the price, this is great, I love it and I know you will love it too :)
