Product review (5 stars): Dries like a full sized unit, and has a variety of settings
I bought one of these used about a year and half ago, and do about 2 to 3 loads of laundry per week.

The dryer dries clothes well.  It has a timed dry, and a "more dry" "less dry" dial setting that seems to involve moisture detection.  When I set to "more dry", clothes come out dry and the amount of time it runs is different depending on what I am drying.

The dryer is not too noisy.  I use it on an open outdoor porch, so that the exhaust and heated air will not vent into my apartment.  The only time it has been noisy is when my husband washed three loads of laundry separately, and then tried to dry them at the same time.  The squeaking noise was the sound of him abusing the belt on the machine.  I discovered what he was doing when I investigated why my loads dried in an hour, but his was taking 8 hours.  So, don't be stupid and try to overload the machine, and it won't be noisy.

The biggest problem with the Whirlpool portable dryer is that the lint filter doesn't catch all the lint.  There is a lint filter I can easily clean and clean after each load by reaching into the back of the drum where I load clothes, pulling out the trap, and removing lint.  When I remove lint, I can see a wire grid behind that.  It separates the lint trap from the air vent that leads to the exhaust pipe.  That wire grid will slowly accumulate lint, and every once in while I have to pick lint out of it with my fingers.
