Product review (5 stars): HERE'S AN IDEA TO MAKE INSTALLATION EASIER...
I bought this because it was the least expensive one which is over 2 feet long and is UL (that's Underwriter Laboratories, the electrical, gas, and heat product safety gurus) rated against fire.  This dryer venr hose s-t-r-e-t-c-h-e-s to about 5 feet before you MEASURE AND CUT.

It had been so many years since I bought one of these NEW (my last 2 came were each giveaways when I bought used dryers from people who were moving far away); well, I didn't think about at least 3 minor details which might help YOU to acheive a quicker, easier installation than I had (and quieter, if you are as loud as me when you lose a little skin).

1)  DON'T skip the 'measure and cut' step.  I know this sounds obvious, but if you are lazy or have someone rushing you, you might be tempted to just stretch it out a little then leave the whose whole and attach the 2 ends, and push the dryer back toward the wall.  Not as good an idea as you might think: even though it collapses after that first stretch it won't collapse as small as it was when you took it out of the box and cut off the zip ties that were squishing it together AMAZINGLY TIGHT.  . So my dryer ended up sticking out past the closet door, into the hallway.  Jack of all trades that I am (in my dreams), I said "no problem.  I'll just bend it in the middle so it makes kind of a "U" shape and then continues in the original direction.  I won't have to go look for my pliers or wire cutters, and the whole thing will work just fine."  That didn't work, either.  Even though the hose easily stretches around 90 degree (and even tighter angles) bends, the inside of the bend won't easily stay tight, so you end up with these huge loops.  That's not a product defect, I know.  It's a "customer who doesn't follow basic directions" type of defect!  If I just left these huge loops, it might have worked for a while, but it also would have been a lot of space for lint to settle (a cleaning nightmare next time the dryer vent is too clogged to let my clothes dry), so I took it all apart, stretched it as long as I would need in order to pull out the dryer next time I need to get back there (about 3 1/2 feet, in my case), cut it with a combination of pliers (for the wire) and scissors for the layers of foil....check out those layers!...then reattached both ends to the dryer and the wall vent.

2) about those attachment points...
My wall vent tube had been cut by either someone very strong and very careless, or somebody who didn't know or didn't care how to use tin snips. Whichever the case, the cut was NOT straight and clean...there were 2 nice jagged edges sticking out.  Probably why my old hose kept getting holes in it (no, I'm not describing a personal problem, ha ha).  So instead of just trying to bend the sharp parts toward the middle of the vent like I did before (guaranteed lint grabber), I used my pliers to fold those edges in and the squeezed them flat against the inside of the tube.  But I don't recommend that strategy, either because of all that I lost in the process (my temper, a little skin off my knuckles, a little blood, and most of my pride of being Mr. Fix-It).  What you should do in that case is to find/buy/borrow a good pair of compound (leverage multiplying) tin snips, preferably ones where the cutting tip is tilted to one side or the other...and cut that edge straight.

3) Both ends of the hose (or just one if you cut off the other end) will have a short section of foil without the wire holding it.  If you are smarter than me (most of you can stop reading, now), you will figure out this was done on purpose, to make it easier to slide the hose end over your vent opening.  Or, like me, you can ignore logic and just do it the hard way.  You should reach inside this end of the hose a little, pull out the "unwired" foil, and stretch it apart so the first part of you hose that contacts the vent is WIDER than the vent tube.  DO NOT assume that the manufacturer made a mistake leaving that unwired foil at the end, and leave it squished inside your hose end as you struggle to make it fit over the vent tube.  What kind of fool would do that?!?

Ok, that's it.  I've said too much.  Bye!
