If you use alternate tunings this thing is priceless.

I can't tell you all how much I love this thing.

Love this thing!Like someone said, it can be a little tricky when changing to/from wildly different tunings, but with some patience, you're fine.

I love this thing!

best thing since sliced toast.

This thing is so cool

I cannot say enough about how wonderful this thing is

This is to keep the motor which powers the tuning capability of Roadie from burning out and is a good thing, but kind of disappointing when trying to tune a guitar.

The Roadie is the greatest thing ever, I wish I had one years ago

The app holding any custom tuning you wish is truly a great thing,

This thing is totally useless

n’t think I would waste my money to try it out
