I ordered this as a cheap clip on Tuner for to keep in my gig bag just in case my rig went down any night - the photos in the ad make the display look crisp and vibrant - however the reality is that it's actually quite difficult to see what's on screen - it's very dim. It might be usable at a dark venue, but definitely challenging in daylight.
The supplied USB cable is white, while the unit is black - how hard would it have been to provide a black one instead?
Additionally, out of the box, mine has a large scratch on the screen.
Sure it's ¤10 euro, but it could have been marketed correctly, and a more appropriate cable supplied.
