One brand that I now avoid - due to poor mechanical design and the logic of their low battery indicator being too-little-too-late is SNARK.

Mine hasn't broken yet, but I know far too many folks that bought theirs and the little arm that holds the ball of the ball/socket joint, or the socket itself has broken.

Mine, it stops working on vibration pickup mode, before the low battery indiciator goes into action. So, I was doing a quick pre-gig check that there was battery life there, and then in the gig - no way to tune (and where I play, the HVAC and lighting changes during the 'set' do mess with tuning of my cheap bass - so mid-set tuning is necessary).

Fortunately, the gig location bought a Zoom B3 bass amp sim/multi-FX which has a totally usable tuner built in, and I don't have to rely on the Snark any longer. It has made it's way to 'use only if nothing else is available' status.
