I’m a real user and this review is real. I’ve used my unit 2x. 2 weeks apart as recommended for older skin. The 2nd time seemed a bit different because the head would heat up to level 3 but after a few minutes cool back down. I would turn it off then back on and it would heat up again. This is a new issue as it stayed hot the entire time the first use. I also detected a faint noise in the beginning of use the 2x that went away. I’m wondering if it is defective already?Of course I’ve not seen any improvement yet. It states regular use could take 6 months to see any.For the time it takes to do several face plus body areas which can be over an hour per sitting (but I suppose I could break it up and rotate areas), Plus now the new issue with it not maintaining the heat, I’m seriously considering returning it in lieu of just going back to my yearly IPL treatments for face and perhaps spending more money on cool sculpting for the body. I’m just not convinced the heat even on level 3 is really doing anything. I’ve had Thermage before 1 x and that was painful and way hotter than this machine so I’m just doubtful this mild warming sensation is effective to stimulate collagen. Unfortunately they only give one month to return it which just is not enough time to see if it works. Giving it 3 stars because it’s expensive (especially if it does not work) and you have to spend such a long time treating multiple areas. If I only wanted to treat one area I guess it wouldn’t be a problem but I think most buyers want to use it on the body and face.
