Advantages: One end can clamp different size fittings. Investments are ok. Cons: Everything else. The color is vibrant and the hose, while flexible, is still a bit stiff and I have to deal with that. But the worst thing is that the hose has swiveling ends, they are too loose and leak too much. The result is a vacuum that is too low. Return it for a refund and get one of these 12ft kits.
