back and shoulders

Im a male and have a very hairy back and shoulders. Ive been thinking about laser hair removal but Im still not totaly sure. Ive heard that it can also cause more hair growth. Has anybody had laser hair removal on their back and shoulders?(males). If so then how satisfied are you with the results? how many treatments did it take to get to the desired level? what type of laser machine did they use? were there any side effects? and any other comments would be appreciated.
Ive also found a medspa where they charge 2500 for 8 treatmens. They use the soprano xl laser machine. Has anybody heard any good/bad things about that machine?

I had my neck done and it didn’t really help, inducing more hair growth… all the way down my upper back.

I advise against it.
