I like this tuner and use it daily to tune my mandolin, guitars and whistles. It is very accurate and responsive. I used it also for fine tuning of my analog synthesizer, and it served great. Downside is plastic material of chassis, it doesn't feel great, it feels a bit cheap. Everything else is great. Maybe light bulb in it could be a bit stronger, but it serves purpose. Needle is very useful for fine tuning instruments, I am a bit old school musician, so needle gives me a confidence when fine tuning (especialy when I work with fine tunning guitar and mandolin intonation).
