The thing wasn't level, it rocked back and forth [left to right] like the mouse feet where not all the same height. I sent it back to Amazon
for a new one. What little I did use, I liked it better than my MX510,

Mine was the same way, leading me to believe they are made a little off. I like it none-the-less, even with the rocking it is a very nice mouse

Yes I could live with it,I find it a little annoying. But will take some getting used to. if they are all like that I wasted time sending it back for a new one.
I'll post if the replacement is the same way.


For what it cost seems like it should be level.

anyone? Is your MX1000 the same way?

Amazon paid shipping on the old one and overnighted the replacement!
There service used to suck, But I must say I'm very pleased with it now.
My new mouse does not rock back and forth like the old one, So maybe they just made a bad batch. It does just very little and I have to try and make it. On the old one I would have to try and not let it rock. A big improvment.
