I first bought from this company 5 years ago, and it still works like new, but when I saw this new model, I just had to have it! I really love this particular model it's beautiful and works great. It has a lot more lights on this model than my old one, and a lot more options on how you want to use it. I'm very happy with my purchase. I mainly use my lights for aging skin. I've used it for 5 years now every day for 10 minutes each day. I am 71 years old but now could pass for 45 years old. My granddaughter who I don't get to see very often, asked if I had a face lift, which I have never had one. I told her it's because of these lights! I have used these lights for pain, and yes they really work on that too!
