Comfortable, easy to learn and use. Buttons and scroll wheel work just like other mice, but with much less joint and tendon strain. Well designed, well made, energy efficient as in the batteries seem to last a long time.
Haven't had this mouse for too long, but I will say that I liked it enough to go ahead and buy another one for my other computer. Seems to be a good wireless mouse at a really good price (around $20 for the green version).
I have used Newegg a lot, and expected nothing but stellar performance, and indeed they performed that way
- Good weight and table-grip keeps unit in place - Adjustable grip angles great for fatigue -Rechargeable, internal battery -Accurate ball tracking
Excellent mouse, very precise, excellent battery life, comfortable feel.
GREAT mouse for the money. For gaming I own another exensive mouse but for the office I wanted a similarly large mouse and this one is pefect. Great erogonomic shape that fits my large hands comfortably.
The price is down about 25% since it first debut a couple of years ago and it's the best trackball by far.
BT connection is stable. Buttons and the wheel are very smooth and quiet. Great fit and fill in my hand. Has a physical off switch to conserve the battery when not used for prolonged time. Battery life is (supposed to be) great - have not owned long enough to judge.
I have selected users request this style mouse and love it for everyday use. I personally like a standard mouse but glad there are options out there.
My 7-year-old son loves it. It fits in his hand better than a full-size mouse, and the bluetooth works better with his old Mac than the usual Logitech USB dongle (with USB-C adapter).
