I understand the hesitation.
Not for everyone.

I actually paid the original price of $80.
For me...worth every penny. And I'm a cheap [*****].
If only for the mandolin. But also the Bass.
Being able to tune while music is playing in the background is a big plus, too (I think)

And the fact that the settings are "sweetened".
Are you familiar with James Taylor tuning video? ...where he explains your B string needs to be flat... that is what these do...



I've spent much more on several pieces of music software that I've never actually used. (How 'bout you?)
I use this every day. On several instruments. It will be my go-to for the rest of my life, I imagine...

So, like I said...for me...worth every penny.
