I bought this a month ago, and am happy I did. For assembly you'll need metric tools, and the correct ones--reaching bolts was impossible with only a socket set or an adjustable wrench. The instructions are poorly written. Attaching the collection bags is a pain, and as others have noted, it's easier with four hands, or some tape which then is removed once the bag itself is clamped. The site doesn't specify that you will have to purchase separately any length of hose at all and clamps to secure it. The nickel and diming is annoying enough, but the lack of documentation means that you then get to pay a separate shipping charge for that and wait another several days for a week for said hose to arrive. All in all, I'm happy with the purchase.
