I've been using this grater for a couple of weeks now almost daily and think it's a really great product. I had been using a own brand supermarket version before this and thie is a real upgrade. Grater is sharp and all the options work well. 

The attachable container is a really handy addition and means I can store any excess until next use. I think this feature is definitely worth a bit of extra cost. I haven't really had a need to use the detachable zester much yet but it also seems a decent addition.
