1. Dulphee A71 Dulphee Guitar Tuner
Battery life is fine and the product is feature laden with an easy to read display. If it's not in good solid contact it may not read at all. Dulphee also has the instruction manual as a PDF online if you need it. I primarily use it for acoustic guitars and ukuleles. UPDATE: Sent it back in exchange for another.
