Product review (3 stars): Works, but could be better
Just as others stated, product has noticeable gaps which will allow dust to escape back into your laundry room. I would suggest positioning the unit to desired length and putting in a small metal screw to secure it so that it doesn't move and then either put silicone caulking or foil tape on the gap areas. One other thing is that my dryer, a Samsung DV42H5400GW has a steam function which requires being hooked up to cold water. Problem is that the inlet which is aligned to the right of the dryer exhaust somewhat blocks the position of the device. Great idea, design is slightly flawed but otherwise I am happy with the product considering the other options.
