These graters come 2 in a set. They have a solid feel with rubberized grips that have a comfortable hand feel. They are sharp, sharp, sharp, which is good but you gotta be careful. The covers are nice and attach securely. They protect both the grater from getting dinged up and also protect you from cutting yourself when they are not in use. The surface of the grater is rounded. I believe this is so that you can more closely control the area of what you are grating. It is nice and works well, it helps reduce the amount of force you need to use to grate whatever you are grating. On the end there is a triangular silicone bar. This rests on whatever surface you are grating onto and stabilized the grater. They are compact and efficient and will easily fit in your dishwasher.
All in all these work well and I would not hesitate to recommend. Full disclosure, the manufacturer provided this product for me to review.
In the video I am making limoncello with the grater. You have to zest about a dozen lemons. This can be tedious and challenging. In my experience this really tests a grater/zester. The product performed well (I am waiting on the Limoncello to sit for a while but it looks good:)
