This is my second WD5/P and a great vacuum for the wood shop. I gave it a 3 instead of a 5 because it was advertised as used in very good condition with damaged packaging. When I opened the box it looked brand new. However, when I assembled it, I noticed that part of the plastic locking mechanism was broken. Looks like it was dropped at some point and then put back in the box. I decided to keep the unit as the top was securely attached to the unit despite the broken part and it is a great vacuum for the price.
