This device turned out to be a lot smaller than I expected it to be, but that's even better. It's super small, light, and portable, and I definitely think it works very well. It's so inexpensive, but is better than any phone app you could download. There are multiple settings, but I've only used it on my ukulele, and it seems to read properly. I also like that it came with batteries. I also like that it lights up when the tune is right, but it stays gray when you still need to tune your instrument.
I like the tuner.It has a large screen and I can very easy to read it even in dark.It is ultra small and lightweight,net weight just 20g.It is very easy to carry to anywhere and keep my instrument in tune every ti1me.The 2 pcs picks are usefull.
