Let's Talk Critique

  I'm almost near the finish line with my novella and ready to get some honest feedback. I've never been part of a critique group and have been searching for information about this. I came across an article in my search titled Can Critique Groups Do More Harm than Good? by Kristen Lamb .This is a well written article that gives the pros and cons of critique groups. 
     It a nutshell among the list of pros are that critique groups can...

•  hold us accountable
• offer professionalism
• take our writing to a new level

   Among the list of cons are that critique groups can...

• become a crutch and prevent growth
• create bad writing habits
• deform a manuscript to the point it doesn't have a chance of publication

  
What are your thoughts on critique groups? Do you use them?
