Query: Pay more & get something better!

I liked the idea of not rolling a mouse around my desk; particularly since i have a laptop and i don't like the track pad at all.The Kensington Orbit was fantastic at first; up and running in seconds, easy to use and feels great in my hand.However, after approx. 3 months use, I find that the left-right action gets stuck very easily and is very hard to start again. Getting the ball out to clean the rollers is easy, but actually cleaning those tiny little rollers is a nightmare, much harder than a normal mouse.Plus, the rubber is so small it is deteriorating really quickly.I discovered the roller itself gets stuck inside the casing and doesn't spring back as it should, so the roller is not touching the ball.In conclusion: you get what you pay for: cheap and nasty!
