Splitting I.

I've tried both Critique Circle Pro and Scribophile Pro.
Heres a few comments about the service for anyone interested in signing up.

1)Scribophile is free
2)Pro is worth it if you don't mind the critiquing.

Critiques:
You can post a piece of crap writing and they will tell you everything thats wrong with it. I got more feedback from Scribophile than from taking a $400.00 writing course from a community college. I'll say this much, the Professor was not engaged and the students sugarcoated the feedback. If I'am paying for a writing course and putting my work out there I want people to rip my content to shreds. They are all very nice on Scribophile minus a troll or two. Some of the reviews are harsh but I prefer harsh over sugarcoating.

Critique Circle Vs. Scribophile
If I picked between Scribophile and Critique Circle I would pick Scribophile. I've seen some professional editors give feedback on the site. This site won't promise you published work, it enhances the work and tells a writer where they need to improve. It's up to the writer after that point.

Karma:

I like the Karma point system. It makes me think twice before posting something impulsively. I also improved my own writing style be critiquing other peoples work. It's like a writing course without the Prof and it's cheaper. The people who have been complaining need to take a writing course with a mediocre Prof.

I see some areas where it could improve, it's a good service that makes even the Pro Members work hard. The critiques can range from poor to excellent, harsh to constructive. Go to the site with a thick skin. You won't be getting feedback from friends tip toeing around major plot holes. If you don't want to spend as much time critiquing this site might not be for you.
