This tuner is alright. It works best in quiet environment. I used this tuner to help when tuning my acoustic guitar. I exchanged it for another tuner. Now I regret it. Sometimes I have to pluck the strings especially the high e several times to get it to register. I was confused with how to use the metronome. It had things like 0/4 1/4 etc. I didn't get that. The metronome was strange because it did not display time signatures . Also the beep sound was unusual for a metronome.
