This pretty little rodent is a great performer,
This review is from: Logitech M235 Wireless Mouse - Black/Grey (Personal Computers)This Logitech M310 is the best wireless mouse I've used.
It's small and perfect to hold with a curvy design, and available in different colours. It's powered by a single AA battery (not AAA as some reviewers mistakenly claim) easily accessible through a sliding panel on the base. It works on all kinds of surfaces, including the leather sofa and cushions. The left and right click functions and the tracking wheel are very positive and pleasing to use.
One of the best features is the wireless USB connector, which is so small and dinky you can leave it in your laptop when you're on the move, and it never gets in the way.
Overall difficult to fault, and offered at a very good price too.
