Product review (4 stars): Not too bad, much better than flex tube
We were desperate for a new hook up for our dryer. Our new house has, as most everyone it seems, an awkward laundry room. Space is of the essence. We initially hooked it up using the flex tubing. But, it was crushed (yes, really not a good idea), and wouldn't hold the connection well. It kept coming undone and was blowing too much heat and lint out, yes, again, not a good idea.  After some research, found this contraption. I initially found the larger one by whirlpool, but it was too long at its shortest, but a little more research and found this size.

I read all the reviews, preparing for the idiosyncrasies of this item. I did a few things I read in reviews:

- measure, with the vent periscope, the distance between the dryer and the wall vent in as close to the position it will end up as possible.
- draw, with a permanent marker, a line on each end where the excess is.  If you have none, just skip all this.
- cut with tin snips, wearing gloves!, the excess. (This is REALLY easy. It's soft aluminum. Just be very careful about the sharp edges!). Could use good, strong kitchen shears too.
- using aluminum tape, duct work tape, not duct tape, tape the edges for safety.  This is needed for when you install it.

I thought that all was going to be a challenge, it really wasn't. Actually very easy.

To install was a little challenge, less than our flex tubing, but not without a little sweat equity.  We needed to slightly bend out the wall vent port. It had edges that kept folding in when we tried to push the male connector in, great idea btw! Once in place, then we just taped around that with the same aluminum duct tape. Easy once we got it in place.

Connecting the vent to the dyer was fairly easy, except that the box edges of this vent can make it awkward.  Our only real concern was that the dryer connection would pop off while we were figuring out the wall vent issues. It is soft aluminum, so it can't actually handle a lot of twisting around before something pops out, off, or disconnects.  But neither could our well tightened flex tubing either......

Overall, despite any complications, this was a perfect solution to our much needed space laundry room.  I recommend it highly. Only lost a star because it wasn't a one person job for us, and took over 30 min to work with modifications we made to make it fit well. Would still highly recommend and would buy this item again.
