Hi-TechReviews looks at the A4 Tech NB90 - a battery free wireless optical mouse. Some of the features on the NB90 include:

  • Wireless connectivity
  • No need for a battery of course - works in conjunction with the mouse pad to transfer power to the mouse using Electromagnetic Induction Technology
  • 2nd Side wheel for added functionality
  • Office Jump Switch - set specific actions for Microsoft Office functions

What’s their verdict?

Okay the way the A4 Tech NB90 works may not be rocket science but it is still darn cool stuff to be able to stop wasting batteries on something as silly as a mouse. I have used the NB90 for three weeks now and I can honestly say that is works just as good as any of those high buck mice do and it is not prone to losing a signal like the MS Intelli Mouse was either.
