Summary: I got the product and received everything in the box including all the mouse weights, but the feet on the bottom are a little more worn out than I assumed from the "like-new" status on the site. Not a huge deal, but I was concerned at first.
Summary: Pros: High quality rubberized material over the entire surface of the mouse. Amazing ergonomic design. Simple, 5-button design. Feels sturdy well built. Weight-adjustment system. Mouse buttons are not too heavy/too light. Custom lighting options. Scroll wheel is accurate and high quality.
Summary: I have finally found my perfect mouse. I have medium to large hands (size 8 surgical gloves), and a wider palm. This thing feels like it was molded specifically for me. Long gaming sessions and ZERO discomfort. I love the rubbery texture. Feels near identical to the Razor material...which is a good thing to me. I like it better than the hard plastic Logitech uses. The sensor is amazing.
Laser has a mind of its own, totally useless mouse

Summary: I got this mouse at the insistence of my Swedish friends, as I do professional gaming on PC. The first one I got had a laser that would randomly go off doing loop-d-loops (not sure how to spell that out) and making the mouse unusable. I got Amazon to send out a new one which worked fine for about a week then started the same problem. At that point I contacted Mionix who said it was a firmware issue and was to be fixed soon.
Summary: I bought this mouse and used it for about a week. In that time it was amazing. Super responsive, fit my hand perfectly, and the weight system gave it good balance. I just tried to update the firmware and it failed. My mouse is now completely bricked and won't be recognized by anything.
Summary: Pros: The ergonomic shape feels nice in your hand, the scroll wheel has nice defined "clicks" at each position. Tracks very well. Build quality is good. Cons: If you pick your mouse up often, then don't get this mouse. The shape that makes it so comfortable, also makes it nearly impossible to pick up. If you do manage to pick it up, you'll likely hit one of the thumb buttons in the process. The LMB and RMB clicks were also very disappointing too.
Summary: Perfect ergonomics. Excellent for ever day use. Not so accurate for a gaming mouse with the positive pointer acceleration that is built-in to this laser sensor. A shame that the sensor manufacturers get away with flaws and the mice sellers align themsleves with those manufacturers and play down the flaws.
