tc electronic PolyTune Clip Tuner

It would be super great because its small and looks good but the on/off switch is so completely annoying that you need a seperate robot arm with a tiny robot finger to turn it on and off. What a silly design flaw.
It does seem to read the tuning well and the clip is nice and solid but it takes so much effort to turn it off when it's clipped on the guitar that is jst isn't worth the time. Buy something else. Trust me.

Pro: tuning individual strings works fine.
Cons:
- even though you tune individually the strings, if you strum, the tuner shows some of the string not being really in tune, specially the low E and G.
- unable to rotate in all directions. Works fine for 3+3 headstocks, but not for 6 inline. If you have to mount it on the side of the headstock, makes uncomfortable to read. It is not possible to rotate it to face you!

Stopped working when in use. No drops or mishandling. Correct usage of battery. Just died. Good features, but under par quality.
