I purchased this wireless keyboard/mouse combo about 6 months ago. In that 6 months I have had absolutely no problems at all. The overall fit and finish is high quality. Both the keyboard and mouse feel well built and strong. When i first looked at this product online the price seemed to be a little high, but once i got it hooked up and started using it I realized why the price is so high. The mouse fits my hand perfectly and has a hefty weight to it, which I like. The pointer responds quickly and has no lag that I have noticed. I also like the low battery indicator. The wrist rest on the keyboard is made with a nice feeling leather material and is well padded. All the function buttons on the keyboard work as intended. The LCD screen at the top is nice and also displays battery life. After 6 months of everyday use (many days for several hours at a time) the battery life for both is still at full! The software that comes with this product is also very handy. It allows you to set macros for each button on the mouse. Very useful for gamers. Overall, if your looking for a wireless keyboard/mouse definitely look into this combo!
