Still chopping by hand...

We have lots of shrubs in the garden needing to be cut back every year - we normally cut these up by hand before disposing of the cuttings.
The idea of a shredder doing this for us, and being able to use the waste on the garden appealed.
We saw the Draper advertised with its abilty to chop 40mm dia cuttings and with a powerful motor and thought that this was the answer.
We started to use the shredder, and within minutes it jammed, and jammed again and again, never actually shredding the material - more like"chewing" it.This was on small branches/cuttings, no where near the apparent maximum diameter of 40mm.
A phone call to Draper told us to turn the blades around - which we did with no improvement. Another call to Draper told us that there had been a number of problems/complaints with the machines, and the offered to look at it for us.It was returned to us a few days later saying that there was no fault with the machine.
Overall, this is the worst bit of garden equipment we have ever bought, and cannot recommend it to anyone.
