I have found the Microsoft Sculpt Wireless Mouse is less accurate than either a wired or traditional wireless mouse. I suspect the reason is the mouse transmits over bluetooth and is encrypted. The encrypted traffic slows the mouse down.
I do not have scientific proof, but I know my experience and it has taken a long time to reach this conclusion. You may not notice this problem in normal word-processing or browsing work.
Keyliner Review: Microsoft Sculpt Ergonomic Keyboard and Mouse Review.
Mouse:
I was reluctant to use this mouse because it was so large and ungainly. It gets tepid reviews, even on Microsoft's site, but I learned to like the mouse, then to dislike it.
A picture about the mouse is worth a thousand words. Once I learned this, I understood the mouse:
In the end, I was surprised; this mouse is noticeably more comfortable than other mouse or trackpad I have used.
If you have an existing wireless mouse, abandon it and use the new mouse. Two reasons:
- The mouse is comfortable. You will be surprised.
- The USB transmitter/dongle handles the keyboard, number pad and mouse. No sense taking up another USB port for a second transmitter for a different mouse.
Follow-up:
I have found this particular wireless mouse is less accurate than wired mice.
I find I am subtly overshooting or undershooting the intended target, and often have to orbit pixels. Definitely not a problem with a wired mouse. It turns out this problem is well-known in gaming circles.
Not all wireless mice have this problem. Because this mouse is encrypted, I suspect it takes it longer to calculate the position. The effect is barely detectable, but it noticeable if you are skilled; especially in drawing programs. The encryption cannot be disabled so there is no way to test this hypothesis.
I have since abandoned the mouse, but kept the reviewed keyboard.
