Product review (5 stars): Great quality and value
I bought this to replace a crappy old flexible vent. The elbow works great so I can push the dryer very close to the wall, my dryer vent connection was a little recessed in the back so it was difficult to get the clamp place far enough in to do anything but I got it as close as possible and pushed the dryer back to where the elbow is being wedged between the wall and the dryer, seems like the elbow is made for that purpose because it has a little fin on it that sticks out so to keep the heat off the wall. Really happy with my purchase, the price is great and it was a piece of cake to install.

One quick note: make sure to check all the clamps on it to make sure they're tight, the ones already on the elbow were not tight enough for my liking. Also it would be smart to wrap the joints in duck tape to insure a tight seal, without tape the joints do seap a little bit of air
