It really depends on what you are looking for in Carbonite. Some of it is broken or has issues, some of them have updates you can write in to fix some of those problems... And for what I do, I have no problems and I still love the addon.
It's hard to get an unbiased opinion in these forums.
Shocked, I'm sure! The only thing I can suggest is to try it and see if you like it as is. If not, follow it, and definitely come back when it is fixed - because Carbonite is the bomb.
