This is a great wireless mouse. I use it on my desktop and it has no connection problems, despite plugging the receiver into the back of the computer. It is smooth and fast. It's really easy to use - plug and play - and it also has a great battery life. This particular model seems a bit bigger than the previous Logitech wireless models, but it still feels comfortable enough for regular use. It was also very affordable.
The pattern is what drew me to this particular mouse. It's really cute and unique. I love the happy flamingos!
