Quality product but just not ergomomic
1 of 1 found this helpful Everything about this product, with one exception, is high-quality: nice big ball, rolls smoothly; nice padding at the base of the unit. But the exception is the most important thing: the unit’s basic design is just not on target. It’s not at all ergonomic for my hand — hard to see how it would be for anything except very small hands. Very puzzling. My old Microsoft Trackball Explorer (TBE) fits the hand well, provides support where you need it, allows a more neutral hand position (no need to torque the wrist to make the plane of the hand flat). But the M-HT1URBK is like a TBE that has been deflated, and then bent to the left. No hump to support the palm — the unit is actually concave at that point. My thumb is left hanging off to the left with nothing to rest against; to do a left click requires poking at the clicker with my thumb. The M-HT1URBK lies flat, requiring wrist torque.
I was hoping this would be a close-enough equivalent to the TBE, but unfortunately it is not

Glasses are very dark
These glasses are very dark -- seem suited for very bright light conditions. Very good quality esp. for the low price. Full wraparound, includes your full peripheral vision.
