An easy to use tuner that has options for "sweetening" your tuning, including "sweetened" tunes for for alternate tunings. I use this and the TC Unitune the most. The one thing I would like to see changed is how the unit is turned off. Currently, it takes a long press of the main button to shut it off, while a quick press results in the unit entering a settings mode. I do not change settings often so it would be more logical for me to have the quick press to shut the unit off and the longer press to enter the options menu. Currently, I have to hold the button down after every tune to conserve the battery. Perhaps the rationale for the quick press to enter the options menu is because most people are constantly changing their settings during a tuning session? I'm not sure.
Overall, it is a good tuner that is easy to use and seems to be very accurate.
