The tuner is easy to use and has a hard grip on your guitar. It only has one button so it's really easy to switch between modes. I use it on my electric guitars and on an electric bass.

It comes with a little battery so you don't have to worry about that either for a while since it's probably going to last at least 6 months, I expect, depending on your use of course.

The backlight is pretty helpful too, everything is easily seen in dark environments. I think it's definitely worth it for the price, I almost can't believe it.

I really don't know if this little thing even has any cons. Maybe the lights could've been done 5% better or maybe less parts should've been made out of plastic and maybe it falls and breaks down in a week, but I really like it, especially for the price and the simplicity.
