Title: Tired of Cleaning
Review: I have to clean off the rollers and ball of this mouse about once a week because the slightest bit of dirt or oil will make the mouse completely unusable. I've gotten into the habit of making sure my hands are clean before I use the mouse, because the slightest residue on your hands from hand lotion or greasy food will gunk up the mouse. Even with regular use, by clean hands, the mouse still needs to be cleaned out about once a week. It becomes unusable if I don't clean it. I truly regret buying this. I do have to say it's a comfortable design, and the infrequent times it does work, it's nice to use. However, the times it does work are few and far between.
