    I think this is a great product. I have ordered 6 for the office and they perform well. I like the feel of a mouse without the wire and don't want to keep changing batteries. This is perfect for our office use.

    Instructions were not available in Spanish. The unit was purchased to replace an older model for use in Spain. I did a rough translation into Spanish and can forward it to you If you want it. However on screen selections will still be a problem.

    Excellent product. Easy to install, just plug it into a USB port. This is a replacement for an a4tech pad I wore out after 5 years use. The round pad design is better than the previous rectangular design. NO batteries to replace, uses your computer power. Highly recommend!!!

    Excellent product. Works well. Sometimes disconnects/lags when using, but only when left on standby for extended periods of time. Also, if mice (the animal, not the computer accessory) are around, keep this away from them. They love to chew on the cable.
    LLOYD -- mcloud, OK   1/26/2010
    Don't know how I ever did anything on the cpt without my wireless mouse. I would not trade it for any higher priced mouse.
    CLEMENT -- coloane, XX   2/28/2009

    good christmas present
    TOM -- orlando, FL   9/29/2008
    Replacement for older model no longer made, works great, enjoy the larger mousepad. Even though this unit does not have Mac drivers, it is still plug and play and can work as a basic 3-button mouse, which is all I really wanted. It was more expensive than the old model, but that is because of the extra features. It is comparable to other multi-function mice, but it comes with its own pad, is wireless and battery-free, and I think it is a good value, especially for the battery-free part.
    ALISON -- weaverville, NC   4/20/2008
    Works with My Mac OSX 10.5 computer system with addition of Steer mouse driver (except second Wheel). I am happy with its performance.
    MARILYN -- cohutta, GA   1/18/2008
    I love it. By this time I would have gone through 2 sets of batteries on my wireless mouse.
    MARY -- arroyo grande, CA   1/9/2008
    My husband loves this Christmas gift. It works beautifully.
    LISA -- warren, MI   1/5/2008
    Easy to set up and use and seemingly works great. Would recommend.
    ALANA -- oak hill, VA   12/28/2007
    Happy with the quick delivery. Works great!
    Hannah -- hacienda heights, California   11/5/2007
    This mouse is so easy to use! It's wireless so its really light! i love it so much because i never need to worry about the batteries issue. the magic pad that comes with it doesn't bother me at all, it makes the mouse wireless and that's all it matters!
    John -- fresno, CA   11/3/2007
    Works really well - I always got frustrated pulling my mouse cord, trying to make it longer. No more frustrations, very happy with this product.
