How many grinders have you owned and how many have of them did you buy yourself

This is a sort of goofy question but me and my friend were smoking and she mentioned that she has only owned two grinders in the 6 years she's smoked and bought neither of them. One was a gift and before that she used her mom's. I also have two grinders, and one was a gift and one came with a stashbox I bought. It got me curious of what others experience was bc I think its fascinating
