Friends and other companies and told me about how great this wireless mouse is and how much easier their drafting task of become because of it. Unfortunately, the company where the mouse would be used uses a proprietary software – written in-house – and there were simply too many problems popping up while using the device. If I were a true draftsman or engineer, or if I used that type of software in my home office, I would likely keep the mouse and use it for many years. I was able to use the mouse for short time on a friend's system and I can attest to how great it is when you have software that it is compatible with. The long and short of it is that the product is a great but proprietary software I'm required to use isn't.
