I ordered a rat 7, but when I went to pick it up today, they had reserved rat 9 instead. The guy at the counter was nice enough to lower the price to what I felt was worth it for wireless capabilities, so I'm now the happy owner of a RAT9.
It's much more imposing, yet graceful in person. I haven't managed to get horizontal scrolling to work yet, but its still much of a joy to use. I use it with no inner weights, and constantly at 5600dpi in windows, at full speed.
I hope replacement batteries will be sold at reasonable cost, since I plan on keeping this one for several years to come. Or else I'll just shell out for a RAT 7 when the time comes.
I was sad that my thumb rest rotation screw was not over the forward/backward screw like in the promotional video. It's located under the thumb scroll wheel in mine for some reason.
