tc electronic UniTune Clip Tuner

This is a good tuner, but I don't like the auto shut off. Also, the first unit I bought died under warranty, and Thomann just sent me a replacement. Thanks, Thomann!

it tunes well, is very responsive and its handy you can just clip it on and tune. I liked using it! Unfortunately mine broke not too long after I got it. The back of it would come off regularly - and then the battery would fall out. I would buy another but they are rather expensive for a tuner... poly tuner is very good too, but again, if they're made of the same materials it may not be the most sturdy piece of kit.
