I have mixed feelings about leaving this review. I love the product, but there are flaws. It is very easy to get tanned from this product. I purchased it because I get skin infections (fungal) every Winter and the medications no longer work for me. I am in the sun in Florida most of the year, but in Winter I do not get out in the sun enough to kill off the fungus that attacks me. UV kills it. So I bought this to keep it under control over the Winter and as a side reason, to keep me tan through the Winter months. I am very dark all Summer long and hate when Winter comes and I start to turn into a pasty white boy. First, let me say that if you are not getting color from this, you are either an ALIEN or you are sitting across the room from it. These bulbs emit UV light in rather large quantities, and there is no way that you will not get tan, unless you genetically CAN NOT get tan. In which case, it is not the fault of the product. I still had a very good tan when I used it first, and I managed to get a burn. I figured my skin could take it since I almost never burn from the sun and have a good tan. I added a couple minutes to the time, which might have been fine, but realized later I was too close to the bulbs. If I burned with a healthy tan on darker skin, please be careful if you are fair skinned.
