Product review (4 stars): Added Thoughts
I found the prior posts to be very helpful.  I had ordered the dryer from Home Depot. When delivered I was told that Home Depot didn't have the side venting kit and the installers weren't qualified to make the conversion.  So, I decided to give it a go myself.  Thoughts:

1)  Anyone with average mechanical ability can do it;

2)  The warnings about cutting yourself are absolutely true.  I found the best solution being to wrap the edge of the two entry holes with blue painter's tape.  Gloves are a problem because you need to "feel" what you're doing;

3)  I have no idea why the manufacturer doesn't make the side venting pipe a couple of inches longer.  As mentioned, once secured, it's impossible to attach the flexible tubing.  I used the pipe that I removed from the rear venting system and cut it with a hacksaw so it was an inch and a half longer than the one in the kit;

4)  It's a real trip trying to wrap with duct tape when the piping is installed; and

5)  There is a very helpful video on You Tube.
