Product review (5 stars): Works perfectly!
We live in an apartment, and our dyer vent wouldn't work even after having it professionally cleaned. Since the building owner wasn't going to do major construction to fix it, we tried this. It works! We can finally actually dry clothes in one cycle. Yes, it makes the laundry room warm and humid, but at least we can use our dryer now. I'd definitely recommend this if you don't have a functional dryer vent.
