Microswitch definitely knew how to market! Definitely some nice graphics in there.
I happened across this article on your site as well: https://forum.trackballs.eu/viewtopic.php?f=17&t=48
This was a neat read, as I use the Kensington Slimblade on the regular. The scroll function is something that I pretty much need in a trackball now. I find it more intuitive that the normal scroll wheel on a mouse. I didn't realize how significant the low height was, and thinking about it I'm pretty sure my wrist would be far more strained if this wasn't the case. Definitely a cool website, and I'll be checking it out if I ever want to purchase another trackball.
