Might as well send your money directly to Bosch and bye-pass the hard work.
Bosch are usually a hit with me, they have failed badly with this machine. The line feed is extremely poor, manual manipulation is the name of the game, the spool and cap has had more attention than a Premier footballer's knee; the cap sticks in place and is difficult to remove; the result is a very frustrating several minutes until you decide to do something else that's easier in the garden.
Read the reviews then look elsewhere until Bosch listen and improve their model instead of the easy root of take the money and run.
