Suction power is great, but the heater will burn your skin
Keep the heat on low.  The picture is 5 days after I used the product for the first time.  I didn't know what it was supposed to feel like so the pain I attributed to the good suction power and not my skin being burnt. I did have the heat on the 3rd setting.  I still wouldn't expect a burn like this.
