Didn’t even notice this thread sorry! I don’t really have the most experience with Soprano I’ve only used it once. I thought you were referring to the actual Soprano which I’ve never used, didn’t know you meant Soprano XL.
In terms of the pain free thing, in single pulse mode you’d want to feel it since it’s like a LightSheer then but no one would use single pulse unless it’s a tough area like face or feet etc. The rapid fire mode does not hurt from my experience. On my underarms it got mildly uncomfortable after a few minutes but it’s a different pain from a laser, it feels more like heat. I’d describe it like putting a heating pad on your underarms tight to the skin then turning it on. You slowly feel it get warmer and warmer and then at the end your skin feels really hot, but not a stinging or snapping feeling or anything like that. My legs I felt nothing at all not even the heat. Also unless they were lying to me, I was told I was treated at the highest settings which is 120 joules, however that works. I did underarms once and full legs once and would never do it again, waste of money in my opinion.
I saw on Groupon recently a place had $89 for 4 or 6 laser treatments with Soprano, it was areas like upper lip, underarms, feet etc all small places. Or you could combine then and do 2 or 3 forearms etc. I almost got it just because I figure $89 for that many treatments is cheap as hell but it needed something like 6 people to buy it to get the deal and only 3 did!
