This Bosch is the one I have https://www.amazon.co.uk/Bosch-Shredder-collection-cardboard-throughput/dp/B00D43EF06/ref=sr_1_1_sspa?s=kitchen&ie=UTF8&qid=1547823862&sr=1-1-spons&keywords=garden+shredder&psc=1
which as you see is on offer on Amazon ATM. It's a truly amazing machine, a pleasure to use - I always try to save up a heap of prunings for my teenage granddaughter when she comes to stay, she enjoys powering them through.
This one has TC in its model number, which stands for Turbine Cut. A cylindrical turbine grabs the branches and munches them up into small crushed pieces. There is a similar model, which you'll se on amazon is cheaper, which has blades, which I haven't tried but judging from past experience is not likely to be so effective as the turbine cut model. See https://www.amazon.co.uk/Bosch-Quiet-Shredder-Cutting-Capacity-x/dp/B001P3NV7A/ref=sr_1_2_sspa?s=outdoors&ie=UTF8&qid=1547824319&sr=1-2-spons&keywords=garden+shredder&psc=1
This is a copy of the review I posted on Amazon.
"This is a very hardworking and effective shredder, which steadily munches up large amounts of mixed prunings with Germanic efficiency.
It works fast, and pulls in the handful you've just fed it, so you can get on with selecting the next stems.
Larger stems are cut and crushed into pieces about 2cm. long, and smaller bits finish up reasonably well chopped and crushed, so they're compacted and will break down when composted.
It is indeed very quiet - it can hardly be heard from the length of our garden - and makes quite a companionable, low-pitched chugging noise as it works, unlike our previous shredder, which made high-pitched screaming noises hard on the ears.
When in action, I couldn't ask for a better performance, and although it's not cheap, I feel sure it will go on working for me for many years. It does have a 3-year guarantee as well.
So why only 4 stars?
It's been designed to go under a worktop when not in use. The top comes off and is stored in the collection box, which sits under the mechanism. this is fine for those who want to store it like that, but doesn't save any floor space and it's more difficult to manoeuvre in and out with the top off, as the handle which swings the weight over the wheels is part of the top section. I don't need this modification, the top stays on in my shed.
It's very heavy indeed, and difficult to move around, especially when going down even small steps. If you ease the machine down on the wheels, there comes a point where its weight takes over and it drops hard on to the lower level.
The collection box has to be replaced correctly under the machine, as a safety feature, or else it won't start. Unfortunately the box doesn't hold very much, and it's hard to see how much has gone in. The machine deposits shreddings in just one area of the box, so when you see you need to pull it out, you find the box is only about half full. Take care also when pulling it out - it needs a firm jerk, and can give your shins a painful knock. Lastly, it';s not easy to transfer the shreddings from the box into a bag for temporary storage or transport. The box is rectangular and you need a very large bag or container to shake the contents into. It's difficult to fit a rubble-sack-sized bag over there end of the box, and not too easy to shake the last pieces in to it. On both our previous shredders, I greatly preferred the option of placing a storage bag or container directly over the exit chute, and then just removing it when full.
The instructions are poor, and really I do feel that, when customers are spending this sort of money, Bosch could afford to produce a more attractive and informative booklet, rather than a few pages on very cheap paper, mainly concerned with all the normal common sense precautions for using electrical equipment. My machine started up OK but stopped running after about 10 minutes. Fortunately my mechanically- minded husband worked out for himself, (no help from the handbook) how to re-set the cutting mechanism so that slivers of metal were shaved off, which needs to be done ready for the initial run. Why this could not have been set up in the factory as part of its quality checks, I do not know.
Am I glad I bought it? Definitely. Its a very good machine and I enjoy using it (apart from emptying the box.) I really like its quietness, its speed and power. With a 1/4acre garden with large hedges and many shrubs, it gives me a sustainable way of managing the pruning without too much strain.
I think its probably the best available on the domestic non-professional market at the moment, and would certainly recommend it to anyone with a large garden and limited time to look after it."
