It took some getting used to, but it's fine. The clicking is easy and quiet. The scroll wheel is nice. The thumb side is a little awkward and cramps my hand, but it's ok now. Maybe I'm not holding it properly, but there aren't any instructions that show how I'm supposed to hold it. I have tiny hands. I can't imagine how someone with big hands would handle it.
This HP wireless mouse works great just as I knew it would. It is really easy to use and is really silent. It is perfect for taking surveys and great for play games. It is a just the right size.
