The tuner works perfect

The tuner works fine, it came along with the battery.

tuner.[U]The Bad[/U]The unit is certainly more pocket-friendly than a Snark tuner but still way too large to comfortably fit in a pant pocket

I tried this tuner and although it works with tuning some notes, I could not read the E on the LED screen
