Perixx Perimice-513L Wired Vertical Ergonomic Mouse - 6 Button Optical Mouse with 2 Adjustable DPI Levels (1000/1600) - Left-Handed Black Computer Mouse for Office Work, Gaming & Graphic Design

Expectations: Since most brands give a hearty "EFF YOU" to lefties, my expectations were to be slightly disappointed while forced into using a modified claw grip, all the while cursing the manufacturer under my breath. This is the state of left handed mice to get a 3 star review from a lefty. *cough*I'm lookin' at you Logitech*cough*Reality & TL;WR: This mouse failed every expecation, and that's why it's a 5 star product.I wasn't forced to use a claw grip to use this mouse, down to two stars.I didn't curse the manufacture while using this mouse, down to one star.Interested in why this is a 5 star left handed mouse? Read on.Lets cover the good parts, and there are plenty...One, this mouse is an actual lefty mouse, no fiddling with settings to reverse the buttons. Is this table stakes? No it isn't. Up one star, making this a two star product.Two, the scroll wheel is nice both for scrolling a middle clicking, once you get past the learning curve (hint: press the middle button with a slight upward motion). The scroll wheel would be outright glorious if the designer had given it a smooth motion instead of the stepper/clicky motion, but it's completely usable. Up from two stars to three stars.As an adult, I can let my fingers relax into a natural position as opposed to adopting a claw grip. Other manufacturers call this "compact," I call it "designed for children in single digit years." Up from 3 stars to 4 stars for considering adult hands.Probably most importantly, is accuracy. This is a wired mouse that suffers from neither lag nor interference. Setting the DPI by the button that DOES NOT GET IN THE WAY, and makes this mouse obscenely accurate. If you spend your day using a mouse in any significant way, you have to appreciate how this mouse JUST WORKS. Up from 4 stars to 5 stars.Finally, if you're looking at this mouse, then, like me, you have a need for a vertical ergonomic mouse. You might not game, or you might be an avid gamer. For me, this mouse relieved the stress I was having, and made mousing comfortable ALL DAY. Up from 5 stars to 6 -- oh, dang! Amazon only allows 5 stars.Long and the short of it is this mouse meets every need you have if you're looking for left handed vertical mouse. Is it perfect? No. Is it next to perfection? For me, you bet!(One nit: Could I pick a different color than just blue for the RGB accent? Yellow would be nice.)
