Mixed review on this one. It's inexpensive, which is great. But you get what you pay for. As an architect and graphic designer who needs precision and comfort, this might not be the mouse for you. It wasn't for me. I need a mouse with programmable buttons and that doesn't feel like it's going to break. It actually came defective, so the scroll wheel didn't work. I will be returning it and buying the Evoluent. As far as "Wow-Pen" as a company, the number given on their Operating manual didn't work, the Q&A section in their website is non-existant, the contact information on their website is incorrect for both US and Int'l headquarters... All in all a questionable affair. Having said that, I want to mention that I spoke with Scott at Ergoguys and he was as helpful as can be! Very patient, nice, and knowledgeable. Thank you for your recommendation and time, Scott. I will be purchasing through you guys. Nothing like caling a number and getting a real person with knowledge and care.
