Product review (1 stars): Would be great item if the vent on the dryer lined up ...
Would be great item if the vent on the dryer lined up perfect with the vent on the wall.  Not sure how common this is but certainly wasn't the case for me.  The dryer still had to be away from the wall quite a ways so the magnets didn't disconnect because of this.  Doesn't help that our dryer is next to the wall with the washer right next to it.  The reason I purchased this was so our dryer could be closer to the wall to line up with out washer.  Because of this issue will continue to use the traditional coil vent hose and am returning the magnetic version.
