The Logitech marble mouse is easy to use and very comfortable. I t requires minimal desk space technically no desk space at all since you can rest it on your leg and works as well as if it were on a flat surface. I first purchased this product for online MMORPG gaming which often runs on click - click - click harvesting and collecting based leveling systems. It was fun at the time and this mouse made my game palying much more enjoyable and reduced the wrist pain inherent with such repaeated mouse usage for hours at a time. ( i was recovering from an injury. there wasn't much to do.) The mouse is large enough to rest your hand over the whole thing comfortably, using one or two fingers to guide the large smooth trackball, your thumb to left click and any other finger to right click. I used it for a few months and was very happy with it before drifting away from online gaming and putting the mouse away for future use. About a year later my sister asked me if i had a mouse she could use and I dug this one out and gave it to her and her 3 boys. I mention my nephews because, as anyone who has boys can testify, they are capable of breaking just about anything. I swear if i gave them an anvil, they would call me a week later asking if I knew how to fix it. They have had the mouse for about 2 years now and it's still going strong. I have never been asked to repair it. Everyone loves it and they complain mightily when they have to use an "ordinary" mouse. The kids do some pc gaming and they absolutely love it. One con: no scroll. It amazes me however, that so few people ever actually use scroll, so this may not be an issue for you.
