Summary: Obviously you are not getting an Apple touch pad for $30, so expectations should be checked. However, the touch pad is more sensitive than other Adesso pads on keyboards I have used and the buttons have a great feel to them.
Pros: Good sensitivity, up/down scroll works well, button click feel is excellent- not too hard or soft, pad responds well to tap-click on the pad and is not overly sensitive to accidental taps.
Cons: Device is thicker than it needs to be, the touch pad feels slightly grainy, the buttons are too close to the touch pad and can make hands cramp over time, no side/side scrolling.
Excerpt: I bought it to replace the use of a mouse at the office. I started to have a strange pain in the shoulder and every back and forth between keyboard and mouse was painful.
I also replaced my keyboard with the Microsoft Natural Keyboard Elite.
Excerpt: This product is small, compact and takes no integration as you just plug it in. It is durable and we use this in a rugged environment which it has done well with no apparent problems in material or functionality.
Excerpt: I have polyneropathy. My hands have very little feeling. It is hard for me to use a mouse. This touchpad allows me to perform cursor manipulation equal to a mouse. One partulicar feature, double-click pad area, provides this pad equal operation to that of a mouse.
Summary: I got this for my wife's new PC I built for her. At work she is used to a keyboard with this kind of pad built in and it's not a laptop. For some reason she prefers this over a mouse.
Pros: Works great! Plugs right into PS/2 port. By moving your finger up or down the right side, you can scroll up or down and to the right and left along the bottom. Tap on the pad or use the left clicker for left mouse functions. Use right clicker as a right mouse button. Works like a laptop pad.
Excerpt: touchpad sensing and scrolls are good.
But it's little bit small and sometimes it's moving when I dragging or scrolling on the touch pad..
I believe it need some sticky thing to fix it a place
