I have very large leaf hedges, to which picking the leaves up after cutting them down can be a real pain. I bought this from Argos , and paid a lot more for it than their own brand.

It was very heavy to carry, and when trying to get the bag attached to the actual unit and you have to kind of force a thin bit of plastic into very small slots at the same time.

It works by using a very high vac, which then passed through a rotating bit of plastic, the plastic rods were very thin and didn't last very long at all. It did struggle to pick up smallish twigs, although leaves were no issue at all.

I bought it in the summer 2010, I came to use it this year bearing in mind you only use them say once and twice. To my horror the unit was sparking and making a burning smell within the unit, it had been stored in a very dry place so cant see a reason for it. In the end I bought a store own brand, it was a lot less and loads better.
