Instead of asking me to pluck out the notes to tune her guitar, she now could test it with this handy little gadget

Looks like a cool gadget

Perfect little gadget for tuning guitar!!

This is a really handy gadget

Really neat little gadget

Works great very handy little gadget for a beginner

I read different comments saying that it is easily breakable, so it kinda worried me as to how cheaply it was made
