Review on Cateck Numeric Keypad & Mouse Combo: Wireless 2.4G Mini USB Number Pad Keyboard and Mouse with Just One USB Receiver - Ideal for Laptop, Desktop, PC, Notebook by Lashawn Diaz

The keyboard is good, but the overall feel and responsiveness of the mouse leaves a lot to be desired. This is the first time I've had to constantly look at my mouse because it's unresponsive or lagging behind. The keyboard feels good. It's small and the buttons have good bounce/rebound so you know you've pressed them. The mouse is made of 100% plastic. It's very light and feels very cheap. The mouse's laser is sharp and unreliable. If the mouse sits for too long (several seconds), registration will take some time, causing the cursor to lag. The USB device has rough edges. It feels very rough when I try to plug it into the USB port. As my situation requires me to move regularly, I feel this will hurt my port. I relied on reviews for this purchase so I have to post my review here. There was a great review from one gamer and I don't see any real gamer using such a mouse, especially due to response time issues.
