I've seen portable Picosure laser machines online for $120. Do you think these would work?

This is unlikely to be a Picosure laser.  In fact, for the price it is unlikely to have Pico technology.  All Pico technology lasers are running over $200K in price.

What do you think the answer is?  A brand new PicoSure is list price at $300,000.  Our minimum price per treatment is $300/each.  I think you should buy one and tell us how well it works.  Your PicoSure will probably have the same power output as an Easy-Bake oven.  Best of luck.
