>Thanks. Those are good points. It's fun for me to see people not use to a trackball attempt to use mine. It definitely took me some time to find it 'natural' with FPS games. It makes sense for you to target a larger audience of potential buyers. Haha I know what you mean, it's also fun to see people trying a vertical mouse for the first time. Even though it's a more natural position, they get so confused. > I love it overall. My thumb joint does get a little sore/tired after long use (nothing compared to wrist pain). So I have considered switching to one that relies on your fingers instead. Also it works on any surface so it's great if you want a 'full' mouse with a mobile device. Ah interesting. I wonder if with long term usage the thumb soreness gets better or worse. I hope the former! Good point about the surface. > I would definitely recommend exploring it as an option down the road, though I'm guessing it's still a relatively niche market. Great to hear this, I'll definitely keep it in mind. > Here's wishing you success finishing and launching your product! Thank you!!
