After 6 months of use I can say it works very well for me!
Even after all the negative reviews I thought I would give a go as it was the only one with the feeder function and this shape/design.
I run a very small office and we shred only about 100-150 pages per week, mostly A4 with a fair bit of smaller slips and this is our 3rd different shredder and the best one so far.
Regarding the feeder the trick is to make a fold in the middle of your stack of 60 pages (1 second of extra work). They will then all be shredded without the need to stay next to it and feed it 3 by 3 as with my old one, a real pleasure! I do the same if I have a stack of A5. For smaller paper slips I usually separate them from my stack of A4 and shred them the standard way. Also it barely over heats.
Emptying the bin is not perfect, but I never had an easy shredder for this. I now know the technique to minimize the mess, which is to shake well the recipient before pulling it completely.
Bottom line, I recommend it and would buy it again.
