Penguin Wired Ambidextrous Ergonomic Mouse - Vertical High Precision Computer and Laptop Accessory - Compatible with Windows and Apple Mac - Medium Black/Silver

I've had this mouse since October 2016 and I've yet to have a problem with it. I've used the Penguin for 8 hours a day, 5 days a week at my job (computer programming). I got a medium and it fit my hand perfectly. I originally started using the Penguin with my left hand. I switched to my left with my old mouse because my right hand and wrist were starting to ache at the end of the day. I then switched the Penguin mouse to my right hand. It was comfortable with both hands and I haven't had any wrist or hand aches or pains since switching.I use the Penguin along with the Microsoft Natural Ergonomic Keyboard 4000. I've used it with Windows 7 and Windows 10, both worked perfectly.The only real problem I have is that I have to manually set the mouse speed with the button on the bottom of the Penguin every time I restart my computer. But I usually keep my computer on for weeks at a time, so this never gets too annoying.July 2019 Update:I actually bought a second one of these for at home, so I'm using this mouse 100% of the time, at work and at home. The one at work that I bought 3 years ago is still working great. Absolutely no problems on Windows 10 1903. The one at home I bought 6 months ago is great too. It's a little bit different in that there's a quicker timeout on the mouse cursor. Sometimes I grab it to move the cursor around and it delays for about a second, like it's hibernating or something, but I've gotten used to it and I'm not going to drop it down a star.I still recommend this mouse to anyone that is having ergonomic issues with their wrist, hand, or arm.September 2021 Update:The first mouse I bought in 2016 is now not scrolling, though I'm still able to click in the mouse wheel. The problem ended up being that the scroll wheel hexagonal axel that protrudes and sticks into the scrolling circuit board was just worn down over time and wasn't catching the sides anymore, causing the wheel to spin but not register any scrolling.I contacted Posturite by email and I got a response very quickly! I asked them to send out a replacement scroll wheel and they got one out to me in 4 days! Getting this thing apart and back together again was a little tricky but I figured it out and I was able to put in the replacement scroll wheel and my original mouse is back to normal!Huge shoutout to Rob and James at Posturite for their great customer service!March 2023 Update:Still going strong 💪🏻 🖱January 2025 Update:I own three of these mice and use them whenever I'm using a computer. Still strongly recommend!

I've been using Penguin Ambidextrous Vertical Mice since 2013 after ditching the Evoluent vertical mouse. The Evoluent mice did not last and were not ambidextrous. After my second Evoluent mouse died, I decided to try the Penguin. It took some time to get used the trigger-style clicking, but after I got used to it, I much preferred this mouse over any other ergonomic mouse I've tried.I have a detailed review on the Penguin Ambidextrous Vertical mouse here:https://www.amazon.com/review/R3NOKEX2VXB9BT/ref=cm_cr_srp_d_rdp_perm?ie=UTF8&ASIN=B00CA21LMWFor those already sold on a vertical mouse and are just looking to choose a style and whether to use wireless or not wireless, I would recommend the Penguin. After you get used to the trigger-style click, you'll note a number of advantages. For one, you can switch from your left to right hand and back again without having to change your mouse settings on the computer. Being able to switch hands throughout the day helps a lot with avoiding overstraining one hand. This also makes the mouse the best ergonomic mouse I've tried for left handers.Second, I find this mouse to be much more sturdy and robust than most vertical mice. It also stays cleaner and is easier to clean.Third, I personally find the wired version to be superior to the wireless version. In the past I tried to avoid wired devices as much as possible. I've since had a change of heart. Wireless is great for printers and other plugged-in devices, but my mouse and keyboard are not wired. I don't have to worry about batteries. Also, many wireless mice, including this one, don't take batteries. If it runs out of juice, you have to plug it in and charge it. With the wired version I never have to worry about it running out of power. This is especially important, because unlike the Apple magic mouse, the Penguin does not give you any warning when it is running low on power.Also, the wireless version of this mouse would often lose its connection to my computer, forcing me to fiddle with the Bluetooth settings to reconnect it.So now I use a docking station with my laptop and have a wired Keyboard (Kinesis Advantage Pro) and my Penguin Vertical Ambidextrous mouse connect to it.My other review complained about the quality of the Penguin mouse, but that was for the wireless version. The wireless version died in under two years, which I find unacceptable for a mouse of this cost, even with heavy use. But my current wired version has been going strong for five years and seven months without a single issue. This is with heavy use and packing it into my luggage for international trips. Because I have to go back and forth between telecommuting in my home country and working overseas for long stints, I'm buying a second one of these mice so I always have one available without having to pack it into my luggage and travel with it back and forth.It is difficult to go back to a standard, horizontal mouse after using this one.I read in some reviews complaints that vertical mice are less convenient for switching quickly back and forth between keyboard and mouse. That will, of course, depend on the nature of your computer use. For me, I tend to try to use the keyboard whenever practical. With the software I use, and my preference for keyboard short cuts, I rarely find myself having to switch repeatedly from mouse to key board.But even when I do, I've never found it much of an issue. Maybe if I were gaming, I could see it being an issue, but I wouldn't buy this mouse for gaming in any event. It just doesn't give the level of fine-tuned control that a gaming mouse does.Overall, the WIRED version of this mouse is a 5-star product. The wireless is a 3-4 star product. I gave the wireless version 4 stars in my review of the wireless version, because it is simply the best mouse form I've found for left handers suffering from RSI. But the frequent loss of connection and it dying on me in under two years, would earn it 2 or 3 stars if just comparing it to mice in general. If having a wireless mouse is not a requirement for you, I highly recommend getting the wired version.
