Product review (4 stars): So far so good
I purchased this for my dryer in my old apartment with no outdoor venting. It is larger than I expected, for some reason, but not unreasonably so. It was easy to install, and the zip-ties are adjustable so you can take them off for cleaning the duct without having to use new ones for reassembly. After trying my first load, my clothes were dry, I didn't have lint all over the place, and there's still water in the basin so I probably won't change it out after every use like the instructions say. I'll probably put a nylon stocking over it just in case, although as I said lint has not (yet) been a problem. I feel like the water-based system helps reduce the fire hazard of just a nylon stocking over the vent, and the duct directs the warm, humid air away from the space behind the dryer and into a more open space that is better ventilated so it is less likely to cause mold/mildew problems. I'll update this review if anything changes but I'm happy so far.
