Product review (4 stars): Be creative!
My outside vent is directly across from my dryer vent but it is at a slight upward angle coming out of wall. This is quite a problem when trying to use the Deflecto HUPK8WA/4. But I really liked the cuffed ends and they did go on fairly easy since I used some advice from other reviewers. For sure put the ends on while the pipe is compressed and follow the arrows on the cuffs for twisting direction.

The amount of pipe I needed was only about 5 inches from wall to dryer, so I cut the pipe to fit but allowed some wiggle room just in case. Since I only needed such a short length I then cut the extended flaps off the cuffs with heavy duty scissors. The remaining part of the cuff has raised seems to grip so that was good enough for my situation. Now if your outside pipe is recessed back far into a wall you will want those extended flaps to maneuver the pipe.

I did need the little bit extra piping that I saved for wiggle room because the wall vent being at a slight angle caused me to have to arch the pipe some while attaching to the dryer outlet. Finally got it!  I still may apply some foil tape to the wall outlet end so that is will never pull away from the wall. So when I pull out the dryer to clean hopefully the dryer vent end will just fall off as it is a little big. I'm also going to put a little fireplace type insulation around the loose fitting at the dryer outlet to keep any exhaust from escaping.

All in all I love the Deflecto Easy...I have a much more convenient way to clean and a much better exhaust then my previous vent. I imagine most people will need to be a little creative to apply the Deflecto in their own situation. But once you finally think it thru you will be happy.
