“Adaptor started off being too tight then went too loose I'm not really bothered by that as it was only for testing. Pi is now hard wired anyway so it's not needed. I did find it useful for my phone though.”
“for all use ( plug into your pi 0 , like to plug into your phone to put usb key , you can plug keypad and optical mouse on your (android +5.0) phone .. )”
“This is a useful bridging device between usb socket formats. Beware the lack of marking as it can be inserted the wrong way and is tricky to get out afterwards.”
