Easy to use, very efficient pruner/chain saw attachment for use with the expand-it engine. I have comfortably and easily cut branches up to about 5" diameter - the angled head makes it a doddle to get to the right place without being double jointed!
To get the most out of it you must pay attention to the instructions about:
(a) method/sequence of cutting - not just to avoid the bark splitting back, but to avoid jamming the saw (which can be a real problem to release again, given that it is at the end of an extension that by definition you can't reach!)
(b) use full revs on the motor before starting to cut
Overall, a brilliant product - and 5 stars for quick delivery too, thanks!
