What blame him?
1 / Its price. But it's worth. I tested in friends and a cheaper copy seen or savings are made!
2 / Its danger. Most blades cut like razors. Do not let little hands up in the house.
For the rest, I have not seen the benefits. It is used more and more we find it convenient. This is not a purchase Xth still to hang in a closet (I'm sure you all have an example of this kind of purchase that almost never used).
Hint:
I almost let myself be tempted by these boxes: ;camp=1642&creative=19458&creativeASIN=B00A5VS3BW&linkCode=as2&tag=leblodeman-21&linkId=JBRROCOGTG4FN7SR
Since many reviews said it was a copy, fragile and that I, on my side, I'm pretty gross, I gave up the purchase.
For cons, I took this: ;camp=1642&creative=19458&creativeASIN=B0000AN4CK&linkCode=as2&tag=leblodeman-21&linkId=GVDBQKPYS5Z5FDR6
The dimensions are not the same but the capacity is almost identical. The product is cheaper and of excellent quality.
I really advise you to store what you will cut your nicer dicer.
