Perixx Perimice-513L Wired Vertical Ergonomic Mouse with 2 DPI, 6 Button Optical Ergo Mouse with 2 Level DPI Switch 1000 1600, Left Handed, black

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.)

Update after ~3years of heavy usage - Overall, very satisfied with the mouse, unlikely I will ever go back to a standard flat mouse post this purchase. The vertical mouse is super comfortable to the wrists. The mouse wheel has started getting wonky, scroll down sometimes results in a scrollup. The other buttons are still fine. Time to purchase a new one. -- After ~1 month of usage. The mouse is angled so that the palm is a near natural position, and helps usage for prolonged duration. While adjusting to the mouse position is almost natural, mouse movements needs some adjustment. The resting pressure point also shifts to the bottom left of the palm compared to the wrist joint in case of a regular mouse. Since there is a DPI switch as well, one needs to play around for optimum settings. The mouse seems to be well built and has an adequate cord length. On the flipside, minor niggles, the mouse buttons are made of shiny smooth plastic, which does not feel nice and is a dust magnet. There is a built in LED that is a bit distracting.

Truly an excellent mouse! I had been using a right-handed mouse for many, many years, and unfortunately, it ended up causing carpal tunnel syndrome. I was pleasantly surprised by how easy it was to switch to a left-handed mouse and how quickly my right hand healed up afterward. I've always preferred a wired mouse, as it seems to hold the button configurations much better and generally runs a lot faster. For an off-brand product, and considering the extremely good price, I would highly recommend this product. This is especially true for any of you righties who are considering switching to a lefty mouse!

Gran producto, llegó a tiempo, el empaque no estaba dañado, funciona muy bien lo reconoció el equipo sin problemas, muy cómodo para esta persona zurda, recomendado ampliamente.

C'est la deuxième que j'achète. Une à la maison et une pour le boulot. Le clic est peut-être un peu bruyant par rapport à la 1ere que j'ai acheté.
