I have had a Roadie for about a year and use it on my uke and acoustic. Works as advertised although the quieter the place you tune the better. My brother in law saw it and asked if he could use it on his mandolin so we made a mando and tuned it up. ONLY time I have ever heard him play in tune with no harmonic dissonance between the doubled strings. I like mine, it is accurate and will tune decently fast.
