Query: The most awkward pointing device imaginable!

I was looking forward to using this thing because of the glowing reviews it received. I couldn't have been more disappointed! What a painful(for my thumb) imprecise and annoying thing this is. It's almost impossible to point it as accurately as a mouse, it's useless for gaming and my wrist is actually MORE tired than with my old mouse because of the constant thumb action. I would give it ZERO stars if I could!
