Question: Is it easy to fill?
Document: Super easy to operate. I bought this for my Grandma and she is loving it! It's easy to fill and adjust the grind.
Looks elegant. Simple instructions. Easy to fill and use. We've been using it for several weeks and it has worked flawlessly. We are very pleased with it.
This is easy to fill works great. Only complaint is that it was a bit difficult to tell which direction the batteries went in, but otherwise, fast shipping, good product.
This grinder works great. It has been helpful during my pepper addicted husband's recovery from surgery. It is easy to fill and easy to access battery compartment. Very handy tool.
I've had this grinder for several months and have had no problems with it. I use it for grinding coarse salt  and it works perfectly. Easy to use and fill. I highly  recommend it.
This is an awesome pepper mill - I have a set of them and have purchased them for my nephew and my sister-in-law. They love them as well. They work great - the light is an added bonus. They are easy to fill and to use and the batteries last a long time. I may get these for my two other nephews as well!
This is a great pepper mill. It was easy to assemble and to fill. It works every time. The "coarse" setting is a larger grind than our last electric pepper mill which seemed to make "dust" instead of coarse pepper. The only downside is the cap, which I find hard to put on.
I bought the Ozeri Graviti Pro Electric Pepper Mill and Grinder to replace a old, electric, bottom grinder model. The bottom grinder always left some residual cracked pepper on the table when it was set back down after use. The Ozeri Graviti is much better  because as a top grinder it leaves the table top clean. It's easy to use and there is no button to push, just invert it over what you want peppered. It is also easier to fill and easy to use.
It is also difficult to fill, but that is not much of a problem when it hardly grinds the pepper to begin with.
This is the perfect pepper grinder! Just fill it with peppercorns, turn it over and it works like a charm. My son-in-law loves it.
Answer: I find it to be a bit of a pain to fill.  You take the top part off (where the peppercorns are) and turn it over.  Because the top is not flat, you have to try to balance it.  And, once it is over, there is a metal post (that allows the pepper mill to work) that is in the center of the area where you fill it. So, you have to carefully add the peppercorns around the metal post.  I use a funnel, but still manage to spill a few peppercorns.  It isn't that bad though - so, I wouldn't let that deter you.
