Anyone got any experience of electric garden shredders that can cut wood

I've got one, but don't use it much. Be aware that the maximum diameter
is of a round straight branch with no side branches. Most plants aren't
like that, so you'll spend a lot of time chopping up branches so they
will go in. Thinner branches can go through a slot, so some side twigs
will go in, but it still won't take anything with substantial side
branches. Mine also won't do much with leafy material - anything not
woody comes through slightly crushed but not shredded.
In the end it seemed much easier to put the small stuff on the compost
heap unshredded, and the big stuff on a bonfire.
