Very Nice [SEP] I just used this product for the first time just now.  I had been using one that I bought 8 years ago, that one was hot on my hands to the point of burning.  This one didn't do that at all.  Warm not hot.  I believe this light is newer technology with LED/UV lights, my old one was UV only.  I prefer this one very much so,  It is compact and very easy to use. Just simply push the button the corresponds with the time you wish, your hand insert turns it on., turns off automatically with the time selected has run out.  Super Easy! I recommend this product for doing any gel polish.
