I don't usually write reviews but this is by far the most accurate tuner I've ever used. Accurate to within .1 cents (equal to 1/1000th of one semitone! it doesn't get more accurate than that) plus it figures out what note you're tuning very fast and is the easiest to use by far. Love the display, the whole thing is built like a tank and should survive decades of heavy road use and being thrown around. Perfect for setting the intonation on your guitars or basses because it's just so accurate.

I have the mini-pedal version. Yes, it's bright. Yes, the display is clear and really easy to discern, even for us old guys with not so good eye-site. Much better than my old Boss TU-2 tuner (which itself is darn good). I love the automatic strum tuning feature - strum your guitar and see all six strings at once, then tune only the strings which are out of tune. No switching is needed, the device is smart enough to tell when you are tuning one string or strumming them all. The pedal is very accurate and also sensitive. You know what I mean - I hate a pedal where you repeatedly overshoot and undershoot the correct tuning - despite having quality tuning keys in good condition. This pedal also works just fine with my bass guitar. It's nice looking and the build quality looks great. The pedal is dead quiet in tuning mode, so I also use it when I need to totally mute my instrument.

Great little tuner. Unlike some other mini tuners, you can easily see the tuner's display indoors and outdoors! I play a fair amount of outdoor gigs, so being able to see the tuner display in outdoor light is critical for me. Today I compared my brand new Polytune 2 Mini to a brand new Korg Pitch Black Mini. Both tuners work great indoors, but I could NOT see the Pitch Black Mini's display at all outside. Deal breaker. The display on the Polytune 2 Mini was crystal clear outside. Polytune is the keeper!

Best tuner I've ever owned. I've had everything from pitch pipes to crappy digital Koss types and even a Boss TU-2.
I was looking to "upgrade" from the TU-2 without breaking the bank... Pretty sure I struck gold! You can't beat 1/1000th of a cent accuracy for $100. In strobe mode, this thing makes intonating a breeze. Or at least as much of a breeze as it can be when you're dealing with flip-flopping climates.
I've only had this for about 8 hours and only got to use it for maybe an hour, but I can safely say, I'm never going back to Boss for tuners. TC makes some good stuff and this is part of the treasure trove!

This is one of the best pedal tuners I've ever owned. With an extremely small footprint, it's accuracy and speed of acquisition is remarkable. It has a very bright display, and is easily visible even for an old legally blind fart like me! It's hard to go wrong with this tuner, and I highly recommend it.
