Catch can not working?

[BigD80]

Do catch cans actually work or is something wrong with mine? I have had an APR catch can hooked up for about 1500 miles now and every time I try to drain it, nothing comes out. I even took it off and looked inside to see if there was any residue. Nothing!! Everyone else claims to drain out quite a bit of oily liquid every few hundred miles. Anybody else have this experience? Maybe I don't drive my car hard enough? Does altitude have anything to do with it? Any advice/experience would be helpful.

I'm actually having the same thing happen. Over 3k miles with nothing yet. Going to have my shop take a look on Monday, ill let you know what they say if its not resolved by then.

I don't baby it by any means but I'm not out there giving it the beans from every stop light either. I've launched it about three times since I installed the catch can as well.
