Product review (4 stars): No Hassle Installation; Does the Job
Purchased this vent because the guys who build my house must have been insane.  The dryer is nowhere near the outside vent and the only way to connect the two was a large, ugly and space stealing pipe.  Pulled the pipe and installed this unit with a much shorter piece of aluminum hosing and I can now push the dryer back to the wall.  Dryer is a Whirlpool Cambrio and the vent fit perfectly.  Mine came with only 1 hose clamp so you may need more but this product does the job.
