Product review (4 stars): Does its job if you keep an eye on it
I purchased this unit 6 months ago.  I vented the unit outside using a very short, straight vent.  The dryer does work for small loads, but does not dry large loads well most likely due to the lint trap.  In fact, the lint trap seems to be holding the unit back from doing a better job all around.

I find with medium sized loads I need to clean the lint trap multiple times to dry well.  This would be fine except that it is difficult to access the lint trap with any clothes in the dryer.  Even without clothes, the lint trap is circular and presses against the rear of the barrel which makes it slightly difficult to access, remove, and replace.  My fiance and I have found one of the lint trap filters rolling around with the rest of the laundry more than once (due to it falling off while trying to replace it).

Cleaning the lint trap can also be a chore.  The manual suggest lint-brushing/vacuuming the filter which works if the filter doesn't get sucked into the vacuum as well.

The unit works better than air-drying and is exactly what I needed in my apartment.  The lint trap/filer could certainly use improved access.  The fact that I can plug it into a regular wall outlet is great.  Make sure to turn other electronics off on the same circuit though.

I would purchase this unit again since I don't have special electric/gas hookups or perm. venting options in my apartment.
