Feature:
This thing SUPPOSED to be a tuner. But that's not exactly true. I find it almost IMPOSSIBLE to get in tune.This tuner needs another tuner to be in tune itself!It jumps all over the place and it shows different value every time I hit it (even I hit the same note without changing pitch or anything!!!). This thing really made me cry and it's my worst investment ever.

Quality:
It's made of plastic and I am not really confident in it's quality.

Ease of Use:
It's really easy to use but then again,there is no point using it.

Overall:
I give it a 3 just because cool LEDs and all that fancy light show... BUT AS A TUNER...STAY AWAY FROM THIS THING. My trueset advice.

Feature:
Features are somewhat limited. It has a small mic, and a 1/4" input and output on it. The flat button lets you tune down up to 3 half steps while keeping the note names the same, and theres a calibration button which has to do with the frequencies or something(never used it). I've seen other tuners in the same price range with the same features, plus metronome and a speaker to play the pitch.

Quality:
It's a bit large, so it might take up a lot of room if you keep it in your case. That doesnt really reflect the quality though, just a poor design. The thing that really bugs me is that the whole row of LED's will faintly blink every couple of seconds if you leave your battery in, so I usually take the battery out after every use which is a pain in the ass.

Value:
There are much better tuners out there for the same price.

Sound:
It may get the job done(tuning that is), if you're lucky.

Ease of Use:
This thing is so erratic, you can never really tell if you're in tune or not. You can pluck a string, and the center blue LED will come on, telling you its in tune, but then it'll keep shifting all over the place. The letter display goes all over the place too. You might have a G, but it'll say C and still be in tune, then it might go back to saying G a bit later.

Overall:
I want a new tuner badly.
