I bought the TriVac from the Worx website to replace a big, cumbersome, heavy well-known competitor's vac/blower and can't believe the difference! Not only is the TriVac less than half the weight, but the metal impeller is a big "step up" for mulching. Much better than the chipped up plastic one in the old unit. The biggest "rave" I have is the simple switch from vac to blower. No more stopping, taking off part A, attaching parts B and C, flipping this and flapping that. Excellent, very usable tool! Only one small comment, maybe offer a bit larger collection bag.
