I have to agree with the Intellitouch crowd. You can read it outside in bright daylight, or inside a cow. The swivel joint is indeed its weakness.
I had a couple of the stick on Sabines, and even a "stealth" tuner that was barely visible, but they all gave up the ghost much too quickly for the dollars invested.
THREAD SHIFT - Has anyone tried the Sabine Bak Trak gizmo. You can record up to 30 seconds of a tune or song and then slow in down to 1/2 or 2/3 speed, while still keeping the same tonal pitch. Supposedly good for learning instrumentals and incomprhensible words. Would like to hear if it does as advertised ?!?
