This is my second machine that I have for travel. It’s super light weight, much quieter than my original machine and never gets hot even when used for over an hour at a time BUT it has a green light that flashes on and off with the pump. Super irritating because I only use the machine at night and it lights up the whole room. Have to put a towel over the vent to darken the room. Luckily the thing has never over heated with the vent covered. Overall 4 stars!This machine does offer continuous and intermediate sucking that can be used for cellulite (continuous sucking) and bust (intermittent sucking). It was false advertising however, that you could use this for the buttocks, the cups are to small for that. I have been using this on my bust and I see some results, definitely plumper, and cellulite a little smoother.instructions are not clear at all.I am a licensed massage therapist and certified in vacuum cupping. I recently purchased this machine and I love it it works great so far the pressure has been excellent and the results perfecto.The machine was broken when it arrived. I was very disappointed.Love the tubing. Time will tell on the machine itself. Great suction now, how it lasts.great price. everything works.Dislike this product. Came with out instructions, no way to understand how to use all the different parts that come with it. I don't know what to do with it. I was thinking this would be something wonderful, is not in my point of view.
