I'd purchased an earlier version of this grater about 10 years ago and, although I liked it, the plastic frame broke after a couple of years, rendering it pretty much unusable.  Consequently, I was a bit concerned about buying the same brand again.  However, it turns out that they have fixed the problem:  this is a very well made, very sturdy grater.  I've been very pleased with the sharpness of the grating surfaces and its ease of use.  Although it folds together for easy storage in a drawer, I usually pull it apart and use it like a flat grater - then there are NO storage issues at all.
