Have you used 4 in 1 ESC?

[Quadcopter102]

I notice a few on youTube builds are using 4 in 1 ESC. I know Emax do them and most of their stuff seems OK - although customer service is alien to them.

So two question you could help me with...
1. Do/have you used them and your opinion?
2. Which did you use and where from?

I have not, but I have heard that you can get ones where you can replace an individual esc if one burns out.

I would go with a more reliable brand. I learned my lesson on the cheap escs.(I lost a quad once, and I am 99% sure it was an esc issue)
