Love this device! Had to quickly buy a replacement when I dropped and cracked the original.

You can quickly season any dish and, using the end cap, grind salt/pepper for recipe use (tsp/tbl). Placing the charging stand near the stove keeps it fully charged and in easy reach. 

I am disabled with some hand issues. The button makes this easy (for me) to use, replacing manual grinders (as long as you pay attention to what you are doing and don't drop it - see above).
