I've used a Clarisonic for 7 years. It's great. I saw this little gadget advertised and mainly thought it was cute. Didn't expect much. It went on lightning sale (which I'd never heard of) and I bought. It is amazing, even better than what I'd been using. Instructions are a little confusing but once you make sense of them, it's a fabulous tool. SO worth the tiny cost. I use it in combination with the Kiehl's Rare Earth and other cleansers and even after only one use, I saw pores reduced in size, particularly around and over my nose, which is the only place you can see pores on my face. It's easy and fun to use and incredibly inexpensive. I hope it lasts a long time because it's become my fave face washing tool. Instructions: Remove plastic over silver end. Charge when it arrives. Hold center power button down a few seconds until the device turns on. Hold down (or click) arrows above or below to increase or reduce vibration. Once device is on, another short press of the on button activates the heat function. I don't really use that but it does work. Wish they had a cold function. Hold power button down to turn off. I think this is a great gadget and would make a nice little gift, stocking stuffer, or aid for teen acne sufferers. I can't say enough good things.
