Review on Perixx Periboard-522 Wired Trackball Mechanical Keyboard With 2.17 Inch Built-In Pointing And Scrolling Feature, US English Layout by Tom Herman

First impression:Best keyboard I have owned so far. Love everything about it.I only regret not getting the fully lighted one, at the time it was more expensive so I didn't splurge.(I got the one with the light only on the scroll wheel which is almost a worthless feature.)I had wrist issues programming code due to mouse clicking.Solved, and no more issues with my wrist while at the computer!I highly recommend this item!________________UPDATE 2 YEARS LATER.Spacebar and Escape keys broke. The keys click and type nice on my fingers, but I swear it doesn't send every letter I type anymore, but typo count is rising. Loses a star, but keep in mind I use it A LOT, so if you don't code every day, it may be 5 stars still!
