price - performance ratio questionable

The grater is really sharp and fits comfortably in your hand. Even cleaning the dishwasher is easy (although we were advised on the purchase thereof).
However, I am bothered truly the margins! I receive in this form, the grated "things" not good from / of the grater. So I do, for example lemon peel difficulties; there is always quite a lot in this U - shape.
Meanwhile, I have seen several other rubbing, which only have a slightly curved shape and not just those margins. Tests revealed to me that even those models have very good handling and are very sharp and I can wipe off the grated Good easy !!!
Well, now I have this rather expensive model - which must now be worn in our household :-)
In subsequent comparison but I would definitely not buy this model!
