However there as some programming flaws as well as design flaws that could be improved

Pros-tunes accurately-tunes quickly-supports many instruments and tunings (be warned some tuning pegs many not for the device)Cons-faulty hardware and programming-not worth 120+ dollars in current state

It had more problems with lower notes on mandolin as well as on the 12string.

If you get this be sure to download the app also, one thing the app did for me was being able to set the tune to top down (high E to low E) vs the default low to high.

The Roadie 2 does a poor job of tuning the Low E, A and D strings, this even after the latest firmware updates.
