I must chirp in:
I've had electrolysis, actually thermolysis for about 30 hrs, with a top rated person, on a high end machine, and IT WAS THE WORST EXPERIENCE/PAIN OF MY ENTIRE LIFE.
So without going into a great narrative, here is simple advice, pain thresholds vary from person to person, test it out first and don't give any money for package deals until you know you can handle it. IT TAKES FOREVER even at 300 hairs per hour. It's like sitting still for an MRI, but with pain involved!!!
I have a very high pain threshold, but my face does not. The technician said I had probably the worst reaction he's had in 20 years.
Now, I'm onto laser, an although that is just about unbearable for me, it's over much quicker, relatively speaking.
I will go with E3000/full nerve blocks for when I have to go back. Oh, and I did topical and injectable anesthetics, no dice.
