I personally haven’t heard of them, but think you are wise to get some feedback from people who have used them before. The idea is similar to what E-3000 uses in Texas.
It says they use an IPL for laser which from what I’ve read is not a true laser, so that would make me a bit suspicious as to their hair removal expertise.
Pain during electrolysis if there is any is generally tolerable with a topical anaesthetic if really needed. Some of the newer computerized machines apparently reduce any pain that might be felt compared to some of the older machines.
I would be more concerned with the experience of the electrologist and their track record. Seeing someone more locally on a regular basis who can guage your skin’s reaction to the treatments, and whom you can go for regular follow ups is probably a good idea.
