where is it made? Taiwan?

Regardless of where this is made there are really only two components to fail. 1) The physical flash drive 2) The housing. The housing is quality, it is anodized, and you will notice a little bit of the anodizing will wear off if you use a 1" split key ring. The flash drive is built like a brick _____ house, and will withstand abuse. The flash drive allows you to speed up transfer speeds up to USB 3.1. For the money this flash drive is awesome.

How well does this hold up on a keyring with car keys?

The question you should be asking is how well will the USB port that you plug the device into hold up with the added mass of the keys/etc. hanging from the end of it. Hopefully, that won't be a great deal of weight - but the USB port really wasn't designed to hold much, and being at the end of the flash drive, its significance will be greater than otherwise (e.g., it's easier to break a thing by placing your weight on the end of a long pry bar than on the end of a short one). If your USB port is low enough that your keys will be supported by the table or counter instead of hanging from the flash drive (and, therefore, the USB port), you may safely disregard this, I suppose.

Has anyone had any problems with this drive recently? I've read some reviews on this that says they experienced a sudden drop in storage capacity

Yes, after a year of usage some of my devices will not read the information any longer. I purchased a 2nd one and had the same issue and it is several months old.

How is the quality of it?

Works just fine! Certainly well protected, as well.
