I bought this pedal as a replacement for clip on tuners, to accurately tune and intonate my guitars and basses. It does that perfectly well.
Pros:
It doesn't jump around, the display is very clear and it functions plugged into my Hotone Soul Press II. I
Cons:
The screen came in scratched a bit: this didn't affect the functionality, but I will be reporting this.
All in all, it's definitely worth it for a recording and touring musician!
