Superduper tuning pedal! The casing is sturdy and it can surely take a lot of beating. You have the dual DC-connection so you can daisy-chain another pedal directly from this, so it doesn't occupy a dedicated output from your power-bank which is good.
The tuner itself is very good. The LED's are bright and clear, making it easy to tune in the dark. And it's easy to find out which string has gone out of tune as you can check all six at the same time, showing which one is off.
I alreay owned one of these, but I bought this one just to have one at home as well. Got tired of dragging it back and forth from the rehearsalroom :)
