FGuid for inventories, yes or no?

Hi, I’m building an inventory system.

I came across the FGuid, so an unique identifier. Is it a alright to use these for inventory systems? The chance of generating the same ID for 2 items is extremely slim, but not 0 (Still it’s like winning the lottery).

I want to know other’s experiences with using these, and if you use them, do you check the existing IDs to prevent duplicates?

Thank you!
