I bought one recently, as in within the last 2 weeks. I love it, almost daily use with no issues so far, just all around great product. I've primarily used it in the A-10C, but I've started to slowly incorporate it into the 16 and 18.
I fly VR, so I bought one of those tactile pens so I could leave little marks on buttons just so I know where my fingers are. I put marks on 5, 0, ENT, comsec, eccm.
