Works perfectly for me.
When you figure that a hand-held electronic tuner will cost roughly $30, this is a bargain. It's easy to use, accurate, and it doesn't take a lot of volume to operate it, even using the mic on a MacBook. It's very easy to pop my MacBook open and tune up, even from across a stage.
Tuned my dulcimer in less than 5 minutes. Simple to use. Worked well with internal microphone on my MacBook Air.
A Simple Tuner that works
I use this with my students and it works fine. I don't find it to take a long time like other reveiwers have found. Also, the input level is adjustable right on the interface... horns thru a MacBook Pro mic seem to pic up fine. My students do not have trouble understanding the interface.
