Regarding the tuning of the classical guitar, it does not immediately catch the low E and A strings. You have to let the string play for about 2 seconds to show.

A simple tuner, it does accurate tuning and is user-friendly. I don't think anyone needs anything else for this price.

In terms of accuracy, of course there are better options, but even with this one, there is no chance you will notice any loss with your ear.
It is much smaller than it appears, check the dimensions.
The build quality is good, it doesn't scratch, and it rotates 360°.
The good thing is that as soon as you are in tune, it turns from red to green. The brightness and contrast are more than enough unless you are in the summer under the sun.
Overall, it is value for money
