Imo - They're all designed to break
I've broken every single one, the plastic around the pin that holds the jaws together usually goes - except for the snark, which I lost - and didn't cry about because it wasn't very good. There is the TC Polytune - pricey and I'm wary of the clip thing breaking. And I see Boss now do one too
I regard clip on tuners as disposable now - useful, but if I get a year or more out of one, I've done well.
Get a pedal rather - they usually have a 'mute' tuning function - so you can tune without signal passing through to the amp. TC does the Polytune in a pedal and there's always the Boss TU3 - which will outlive the sun.
