Product review (3 stars): ... duct and the canister itself is not of the best quality (the top portion
Photos in the description seems to illustrate a longer metallic duct and the canister itself is not of the best quality (the top portion, didn't clip to the botton very well on one of its sides). Clamps are made of cheap plastic and they broke almost immediately.  I advise you look somewhere else for this type of product.
