Product review (5 stars): Worked Perfectly!
This worked great for side venting my dryer!

One thing the instructions don't mention, that you might want to do (before installing, unless you plan to take the dryer drum out to install. I didn't!), is wrap the intersections of pipe with aluminum tape.

I did this due to the fact one end of each pipe is crimped so it will easily fit into the uncrimped end of another piece of pipe. Seems like if this was not sealed, my dryer would be a lint farm after two loads of laundry.

Better safe with a little extra effort, than have a lint fire, IMO.
