Summary: I could not get this to work on my laptop. Bluetooth connected easily, and laptop was recognizing the device as "working properly", but nothing I did could get this to work (either as a mouse or trackball). I even uninstalled and reinstalled. I had to send it back.
Summary: 17 months and still very pleased. I was worried about buying this product because of the negative reviews associated with cleaning the trackball. Then I found one review that explained that with some care it was possible to extract the trackball, clean and replace it. I have found this is not necessary if you follow some simple daily maintenance. With a moist cloth rotate the trackball in all directions every day.
Summary: This was a beauty out of the box. Pros: It synched pretty easily once I figured out what the lights meant. Unlike other bluetooth mice I've had, you don't have to go through a lot of fussy set up every single time you use it. Once it's paired, it's good. I have had it about a month and never even shut it off, so the battery life is great. It's also got a handy little off switch on it so it won't accidentally turn on when you travel and be dead when you arrive.
Summary: I really liked this trackball / mouse - best of both worlds, working in every situation, and bluetooth. When it is working - it is great. BUT - first one died after several months; I ordered second one as I liked it so much, thikning first one was a lemon. When this one died too out of the blue, and just after a few months - it is really unreliable piece of HW. Functionality wise - great, but I would not get another one, and would not recommend it to anyone.
Summary: Bought this mouse as a travel trackball. Can't seem to get it to function as a true trackball, and can't seem to find a detailed owner's manual on the CD. Works great as a regular mouse, though. More time may allow me to figure out how to make it do its tricks. I haven't had it long enough to report on battery life.
Summary: I have been a Logitech trackball user for years and years now. And with that it was very hard for me to get used to this. Honestly, my wrist would not get comfortable. I would get a bit of a cramp in it and found myself taking a break here and there. As for the bluetooth I kept having troubles. I would leave it alone and sometimes it would connect and other times it would not. Sometimes it was only left alone for a few minutes.
Summary: This is my first Kensington mouse after having used various Logitech models. I bought this after trying a friend's. The scrolling ball is heaven and covers a lot of screen real estate with little effort. Side to side too! My only hesitation was all the reviews mentioning how it could dirty and stop functioning. The things got a good warranty and after a month or so I just don't see it as a problem (don't eat greasy fried chicken while surfing lol).
Flawed - Trackball wont last long, no way to clean

Summary: I bought this 6 months ago, until now I have been impressed with the mouse probably rating it around 3 stars. Now what has happened is the trackball has gotten dirty. I have used trackball mice for about 10 years now. Yes they all need cleaning every few months, finger oil, dust or whatever gets stuck in there. Now I only use my trackball on this mouse for scrolling.
Summary: I've used the full sized Kensington Trackball for 20+ years and have been extremely satisfied. I wanted a Bluetooth trackball for my laptop and, of course, it needed to be smaller than the desktop model. The SlimBlade Trackball fills the bill nicely. It isn't quite as handy as the desktop version due to the smaller size and lack of a dedicated scrolling "wheel" but for the purposes most of us have when using the laptop it works well.
