No way am I able to clean that without a bottle brush. I’ll sick to a standard mug.

I have a tiny Kingston microduo 3c drive on my keychain with some tech toolkit stuff. It is small and robust. Think I have had it knocking around for the last 4 years.

Sorry for your loss. I hope you have multiple backup copies of those files somewhere. The flash storage on those drives are the cheapest of the cheap and it isn’t unheard of for them to go belly up suddenly.
