Microsoft Sculpt Wireless Mouse less accurate

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.


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.


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.
