This tuner is really simple to use ("On" button and that's it, although there are more adjustment possibilities, and also works quite accurately.
It's small, arrived with batteries included and also well packaged and quickly.
[The company even sent a note that you should evaluate them well (great propaganda), but here I do it gladly, because it really can not be anything other than praise. Securely packed, delivered quickly and with gimmicks.]
+ Good Akkustikempfang (you can also tune his whistle sounds so ^^)
+ Lightweight yet durable
-no
In short a good tuner that does what it should and not for too much money.
Have Fun.
