Lekvey Left Handed Mouse, Wireless 2.4 GHz USB Lefty Left Hand Ergonomic Vertical Mouse, Less Noise - BlackCarbonfree Certified

I was skeptical about this type of mouse. It is an absolute game changer and life changing. This ergonomic left handed mouse solves many issues when comparing to the standard mouse. I have less pain in my wrists, it relieves fatigue and I can easily use sitting up or laying down. It's sleek and ever so comfortable to use. I have ambidextrous mice too and adding this Lekvey was a less expensive compared to my usual brand. It took a little while to get used to use and train my hand in that position. Within a couple days of use I got the hang of it. This mouse is on point and with 7 solid months of use, this mouse is a great addition to my laptops and computers. It works smoothly and it's literally just brilliant. I highly recommend this to anyone who is a leftie, and needs something unique, functional, comfortable and life changing, this is for you. I'm highly satisfied with my purchase and I am in the market for another version of this but rechargeable.

Loving my new left handed mouse by Lekvey! I have this mouse for work as i have tendonitis and needed an ergonomic mouse! This mouse is a savior for me. My wrist does not hurt anymore and i can be on the computer for 8+ hours per day! It just takes a little getting used to.1. I'm enjoying it's ergonomic feature, this mouse allows your wrist and hand to be in a more natural position. Not bulky and heavy like some of my previous mouses. It's affordable and comfortable, which is pretty much all you need for an everyday mouse.2. Lightweight but sturdy, The clicking noise is extremely quiet, the buttons are soft, and the scroll wheel (ball) is smooth and moves easily. It's a joy to use.3. The mouse is plug and play, and very easy to use. Takes 2 AAA battery (not included) and the receiver is located next to the battery. After you insert the receiver into your computer USB port, it takes only seconds for it to set up.Additionally, I do like how the usb connector can be stored inside the mouse, great for traveling or on the go!This is the most comfortable mouse EVER. I highly recommend this product especially if you are having pain in your wrist from typing and using a left handed mouse.

Pros:- Feels comfortable, ergonomic- Powers on and functions as intended (mostly, read below)- Sleep function keeps battery from running down- Inexpensive compared to other brandsCons:- It will reset your computer's settings (not the easy to change ones, the background menu settings) to a left-handed mouse orientation. I mouse with my left hand but keep the buttons right-handed so I don't have to re-think my mouse if I use a co-workers machine. Having to change this every time I boot up my machine or plug this mouse into a new laptop kills me.- Some things just don't work with this mouse or it has issues with some programs. For instance, I use remote desktop for work. When I boot it up, I need to move it to a new monitor as I don't use RDP on my main monitor. To do that, I typically click and drag the blue bar at the top to the new monitor. However with this mouse, doing so freezes up RDP. I have to go into task manager to get it unstuck. I can click the little box to un-maximize RDP and then drag and drop but if I click the blue bar when it is maximized, it freezes things up. There's other issues on precision clicking. I can click the corner of a window to expand it diagonally but the window will only move vertically or horizontally (or won't expand at all). Little things like that make this a deal breaker as I need a mouse that clicks what/where I want it to without issues.------------------------------------Follow-up: After posting this review, the seller reached out with a make-good offer. I wasn't expecting that but I'm adding back a couple of stars for after-service support and help. It's refreshing to see someone make good on their product after negative feedback.

I have been using mice since 1985, so my hand has needed considerable re-education, but the effort is proving to be worth it. I'm a lefty who once broke her left wrist, so it's not aligned quite right; after a couple of hours of work, my hand would go numb, with some bonus wrist pain. I just got this mouse yesterday lunchtime, played games with it in the afternoon to acclimate myself to the mirror positioning of the buttons, then did a few hours of work after dinner (I do 3D modelling). And at the end of the evening, I had no pain or numbness.After 30+ years of using mice mapped for right-handed people, the button layout is still tripping me up, but I appreciate that the LMB is now under my index finger, and the extra buttons are easily accessible from my thumb. The whole mouse sockets perfectly into my hand, and, what with the racing stripe and the dorsal fin profile, it's a totally hoopy device.Update (27 September 2018): The mouse's scroll wheel has gone weird on me in the last couple of weeks -- jumpy in either direction, unreliable. I use Blender software 3 to 6 hours a day, which depends on the scroll wheel as a middle button, so the wheel has had heavier than normal use. Also, my hand has tended to slide back into a vertical position while I work which means I've been putting unnatural amounts of pressure on the wheel from the wrong angle. The mouse put up with this punishment for about 6 weeks. Perhaps the company could look into this, because I'm not likely to be the only customer with ingrained usage habits...That being said, my hand and arm feel much, much better since I started using this mouse.

pay attention to all the fine print. no batteries, no Mac OS support. uswless as is.
