Mate I bought it as a wonderful miracle solution to the bikini line dilemma with the possibility of whipping it all off with it. I got one side done, oh my god, so very very tearjerkingly painful, and had to give up. Having your pubes ripped out by the root isnt good. I had a wonky triangle for ages.
I hate waxing and get bored with shaving so I might buy a better one and try again sometime.
You should totally get a chargeable razor thingy.
Only, don't heed the instructions, like. If it says that 'under no circumstances apply shaver to skin while plugged into the main electricity supply', then you should totally do the opposite.
It's self-electrolysis and can't be anymore painful than waxing, I would imagine. Just think of it as an anti-vibrator.
