Query: Going back to wired mouse

This mouse COULD be great. But after having it for almost a year, I am so sick of changing out the batteries too often, having the scroll ball get dirty WAY too often, and occasionally it simply doesn't work when clicked even when it is still visibly mobile onscreen. The idea was great but the function doesn't measure up enough to put up with this any longer. Unless you own stock in a battery company and don't mind continuously cleaning out the scroll ball, I'd advise you to look elsewhere. What a shame, I am a diehard Mac lover.
