Product review (3 stars): All in all it works well. I gave it ...
All in all it works well.  I gave it a three star rating for 2 reasons:
1:  The joint from the 90 degree bend piece to the piece that sticks out of the side of the dryer would not go together at all.  I had to do some serious cutting with tin snips and reshaping.  If I didn't have tin snips then I would not have been able to do this.
2:  The piece that sticks out of the side of the dryer was not long enough.  I am not sure if this is because I had to modify it as I stated in reason 1, but it only stuck out of the dryer about 1/8 to 1/4 of an inch.  This was barely enough for me to be able to attach the dryer vent tube to.  Because of this, getting the dryer vent tube attached took longer than the rest of the project combined.

I would buy this again because there is nothing else to take its place.
