I have a stick dangeling on my keychain too, also in heavy use. But due to my Mac-Friends i need one with usb-c. So I settled for this: The hinge is still holding on since almost a year. Also have two of those: But they seem a lot cheaper, flimsier and I probably got ripped off by a dropshipper.
Havent benchmarked them, if anyone knows of a comparison as good as this one for "dual" usb sticks, let me know!
Not OP but the first three things I already experienced today were: Knee and backpain, standing out in a crowd, needing to slightly bend down vor everything in most standard kitchens.
