We can only judge a service when something went wrong. If something went wrong and the company delivers an excellent after sale then we will promote it.
When somebody does something right from the first time we do consider this normal.
On the personal side: well I was born with 2 left hands but trying to do as much as possible myself. And to honest it has a steep learning curve, we save money and my self esteem increases! But when I do consider it to big a task or to risky to do more damage I will hire a professional!
Yeah, we don't want to self-operate on our bodies, we should trust a doctor for that :P
Even if I wanted to do this, I couldn't. I would have fainted before the first cut was made :)
