How long you use it?
8mois

Did you tried many other models before buying it?
I used the TU-2 Boss from home

What is so special that you love the most, least?
I'm not going back on the technical characteristics of the machine but I bought it mainly for the poly function, used on various tunings, (they're not alone I am given half a tone lower!).
This function is, for my part, very useful live: gain time to retune! based on "single string" I find it much more responsive and accurate than the TU-2.
So to summarize:
the +:
True-bypass
Poly-mode very useful live
-Very good readability and visisbilité
Precise-

the -:
I've noticed a very slight lack of precision when I pass C # on the E string serious in granting me with the pick, fault has been corrected with the thumb
She does not have integrated bottle opener (also other tuners either!)

How would you rate the quality / price?
Bought new (about 80 euros), it is in the price for a pedal tuner. And it does very good job!

With experience, you do again this choice?
YES!
