I can't praise this product highly enough (although I am probably about to). I used to use a Black and Decker hedge trimmer and cutting the hedge was always a chore - each area needed three goes and it took forever, and the results were never that brilliant.
In fact I thought it was my fault that the results weren't good, until we got this new Bosch hedge trimmer. It really is the bee's knees: the blades are super sharp (careful now!) and 2 feet long, so they cover a much longer area with each stroke, and the sharpness means you only need to run over each patch once. It has literally halved (or more) the time it takes me to cut our hedges. I wouldn't say it's become a pleasure, but it's certainly much less of a chore.
The collector is a useful attachment, but only for doing the top of the hedge. Then it gathers the trimmings as you go along, and you can just tip them into your bin as you go.
All in all a superb product which has transformed my gardening duties!
