It was only a few weeks ago that the drive was reporting the capacity but was not readable, now it won't report capacity either.

There is nothing probably worth spending a lot on for data recovery, I was just interested to know whether anything more could be done with it myself.

If Testdisk cannot detect the drive it cannot do anything. Is there anything that can be done for a USB stick that says No Media and is undetectable?
