The F8 works fine for basic recording, I was an early adopter of the 1st version as a test. Now it sits on a shelf in my gear room as a backup to my SD 688.
If my 688 went down I would have no problem using the F8 until I got it back. Just sayin...
Got mine last week. SOFAR LOVE IT!. Using it paired to a tcx-2 transmitting continuously jammed from my 688.
slightly smaller and more refined than old faithful ts-c.
Comes in a hard storage case as does the tcx-2.
How it holds up ...Time will tell...
