Product review (3 stars): Does What It Needs To But Cheaply Made...Be Prepared To Buy Other Supplies.
I have essentially a closet where my washer/dryer fit in my home with bifold doors in front of them. While I made the effort to purchase the narrowest standard dryer possible, when I went to connect the exhaust vent, I still ran into problems with depth. A standard 4" vent hose needs about 7"-8" to actually make the turn up and out, and that would not work if I wanted to close my doors, which I do.

This product was recommended to me by someone at the hardware store. It is in fact, MUCH slimmer than a traditional hose (Approx 3" when installed) and allows for me to push my dryer back into the area so I can close the door properly. However, be prepared to purchase some other items when you buy this product to get it to work.

Firstly, the construction is pretty cheap. It is made of VERY thin sheet metal such that it can crush if handled too roughly. It has an adjustable sleeve that you can move up or down to get the Vent Out to a height that is above the top of your dryer so you can connect a traditional vent. The cuts & folds of the unit are cheap such that there are A LOT gaps and the air flowing through the vent will escape making the rooms surrounding your dryer very hot. I had to take aluminum ducting tape (not to be confused with duct tape) and basically re-wrap the whole unit to cover and seal all the gaps so hot air doesn't escape.

I would also recommend picking up some vent clamps with this as well. You will need one to secure the base of the unit to the Dryer Out (which was a PAIN to get tight enough to the point where it would not fall out) and also you will need one to connect to the traditional 4" Vent at the top.

Overall, the product does what it needs to but for almost $35 I would have expected something sturdier and better made.
