The Hamilton Beach Burr Grinder is a great multifunctional product. It is compact and doesn’t take up a lot of counter space so it fits nicely in my coffee area. I like that it has several grinding settings as well as setting how many cups I want to process in one go. There is a lock mechanism for the top container to keep things in place before the grinding process starts. However the lock orientation was counterintuitive to me—the lock position is where I thought unlock would be and vice versa. The container that the grounds go into, at first I forgot to put the lid on it before starting the grinding so it all sprayed out but once I got it right, it worked perfectly. I not only use this for coffee but I like this for grinding spices too. It works really well for both coffee beans and spices and it gets a lot of use in our kitchen.
