1PCS Japan EVQWJN007 Blackberry trackball mobile phone navigation key multi-directional multi-function rolling ball

Fast shipping, 100% as advertised. I would whole heartedly recommend this seller.

for replacement of the stock uConsole trackball, I recommend getting multiple, 1 was almost worse than the stock, 2 was sorta better, and last two was smooth, colour didn't match 100% from the picture. But now I don't need to feel like Im doomscrolling to move the cursor 1cm on the uConsole.

Nice

Good

This worked to replace the dead on arrival trackball in my Clockwork uConsole

Track balls not moving much and some barely move the mouse pointer and other dose not move down direction
