Pros: - Good working range - Trackball and buttons are located exactly where your arms expect them to be - Rare type of product that incorporates trackball, not the tuchpad

Cons: - Manufacturing quality: The trackball was trying to fall off, the keys were hard to puch, the edges are scratchy. Everything looks cheap. - The keyboard dropped RF module every hour, tech support said "try reconnecting, if it doesn't help, try reconnecting again", sometimes you have to press a key twice to make it work, which makes reliable typing and even point-click surfing very hard. - If you play games with keyboard you are in trouble. Continious pressing of any key makes keyboard think it is accidential keystroke and the key is "depressed". So for example pressing accelerator button in racing games is problematic. - The keyboard layout is confusing. No blind typing is possible, the keys are bit smaller than on strandard keyboards and dislocated so you will press wrong buttons. - Finally the keyboard broke after 2 weeks of usage so the trackball that was not working well before just stopped working at all. Currently I am waiting for refound and searing for better product

Overall Review: I've seen exactly the same kayboard on <well-known marketplace, starts with "e" :) > sold under different brand. You can make your own conclusions :)
