PerixxPERIMICE-713L, Wireless Ergonomic Left Handed Vertical Mouse, 6 Buttons Design, 3 Level DPI, Black, Medium

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.)

[No compensation of any kind was received in connection with this review.]Old age and years of pointing and clicking have left me with moderate wrist pain if I use an ordinary mouse. I began exploring vertical mice a few years ago and, as I'm left-handed, the field of contenders was pretty small.I first tried the only offering from the BigBrand mouse company. It eased the pain, but that mouse is a very poor match for my left hand: it seems hard to grip, awkward to maneuver, and my thumb can't reach either of the thumb buttons. Also, the BigBrand vertical mouse is way too expensive.Then I found the Perimice-713L from Perixx, a company unfamiliar to me. This mouse feels just right in my hand, it points, clicks, and tracks exactly as it ought, and the price is about one-third of BigBrand's.I've used the 713-L with three variants of Linux (Kubuntu, Fedora, Debian) with no difficulties at all. In fact, I've got just one suggested improvement, and it's quite minor. There's a switch that selects one of three DPI levels; I wish there were an LED that signals which level is currently selected.Would I buy another one? I already have: I've now got three of these Perixx mice, one at each of three different locations.Try to find a way to handle a vertical mouse before you buy one. The BigBrand mouse is good, in most respects, but it's plain uncomfortable for me in daily usage. The Perimice 713-L works far better in my hand; that it costs only a fraction of the BigBrand price is merely a bonus.

I had surgery on my right shoulder and needed a left-hand mouse for awhile. When I saw this mouse at its price, I decided to take the opportunity to try out an ergonomic mouse as well. I found a mixed bag.Most of the positives have to do with the quality of the mouse for the price. It seems to be decently constructed of good materials and, despite taking a number of tumbles to the floor (more on that later), has held up very well. I have been buying expensive mice for years and I've got to say that this one has really surprised me in a positive way. If you're looking for an ergonomic mouse for a decent price, this is one you should seriously consider.There are some negatives, and these mostly have to do with the facts of life with an ergonomic mouse. The concept is good, but it's taking me quite a long time to get used to the new hand position, which results in my not having a good grip on the mouse and having difficulty clicking either button without moving the mouse, and a lot of difficulty double clicking it and having the computer recognize it as a double click. I believe this has more to do with my adaptability and learning to use my left hand than with the design of the mouse.But, when I get it right, the mouse is very comfortable in my hand and works quite nicely.Similarly, I'm having trouble moving the mouse pointer or cursor accurately. I'm also having trouble adjusting the dpi. There's a button and their advertising mentions that there are three different resolutions, but the instructions that come with the unit are very sketchy and do not describe how to adjust the setting at all. You're on you own on this one, and I'm not sure that I've figured it out yet myself.An ergonomic mouse is considerably higher than a traditional mouse. Keep in mind that if you are using your mouse on a retractable keyboard/mouse tray, this may require you to have to lower the tray in order to allow room for the mouse to fit when you slide it under the work surface.And, one final detail: The additional height of the mouse also means that you have to raise your hand higher to get it over the mouse when you move your hand from the keyboard to the mouse. I seem to forget this often and so my mouse hits the floor frequently when my hand knocks it off of the tray.Recommendation: If you're looking for a good quality ergonomic left-handed mouse, this is one to consider.
