The Q pipe is actually made by Matt Shearer.
They also haven't been on the scene for long, they've been out for at least 5 years that I know of but no more than 10 years.
You're much more likely to get shafted by Dr. Q than Shearer, just the facts.
I've never actually heard of anyone giving Shearer negative feedback, Q on the other hand has screwed over dozens of people on this very forum...me included.
