Lekvey Ergonomic Mouse, Vertical Wireless Mouse - Rechargeable 2.4GHz Optical Vertical Mice : 3 Adjustable DPI 800/1200/1600 Levels 6 Buttons, for Laptop, PC, Computer, Desktop, Notebook etc, BlackCarbonfree Certified

I originally bought this mouse years ago and loved it so much I repurchased it after leaving mine behind while traveling. The ergonomic vertical design is legit — it completely changed how my wrist feels during long work sessions. If you deal with wrist strain or carpal tunnel, this shape makes a huge difference.The 2.4GHz wireless connection is super reliable — never had an issue with lag or dropped signals. Setup takes seconds. I plug in the USB receiver, and it’s ready to go with my laptop, desktop, and even my travel notebook. Battery life is impressive — I charge it maybe once every couple of weeks with regular daily use.The DPI button is a great bonus, letting me adjust between 800, 1200, and 1600 DPI depending on whether I’m working on spreadsheets, designing, or casually browsing. Six programmable buttons are well-placed and make multitasking easy.Build quality is solid. The matte finish feels nice, and the mouse has a smooth glide without being overly sensitive. For under $20, this is a ridiculously good deal. Honestly performs better than some $60+ ergonomic mice I’ve tried.If you’re looking for an affordable, no-drama wireless mouse with solid specs and real comfort, this one’s it.

I have used this mouse for about 3 months now. I'm on the computer (on average) 3-4 hours every day. This mouse is working great for me. The battery lasts a long time. Most importantly, it has significantly helped with my wrist pain.

This is my first ergonomic mouse. Wish I had tried one way before now. I dont know what my hold up was, maybe because they looked weird and uncomfortable, haha. Well I know what prompted me to try one: my wrist has been bothering me, and it seemed to be made worse with mouse use. I guess all my gaming years have added up.I didnt know which to try. So many! I didnt know what would fit. There are some really small looking ones and some that look bulky, some that are nearly same in appearance as a standard mouse, and some that have a deeper cut out where hand rests. Very confusing. So I just spent some time reading through various reviews of a wide assortment of ergonomical mice.While I think some of it is trial and error for getting the right fit, I think I happened upon a really good fit and feel with my first try. I really have nothing to compare it to, but so far I am really quite pleased.--I dont have small hands, but they aren't exactly big either. Size can be in length and width. I have quite small fingers, but wide palms (3.75"). So typically a size "large" in gloves, but the ends of the fingers always dangle quite a bit. Hope that gives impression going forward with my review:--My hand easily grasps the width of this mouse. Feels very comfortable. My pointer finger just reaches the scroll wheel. I dont need to reach for it; my finger pad sits directly on top of apex of the wheel.--Press of left or right side is easy and comfortable. Plenty of length to accommodate even the smallest of fingers. Yet plenty of spare room for fingers longer than mine.-- Not a loud click, but I can feel the click. I personally find that satisfying. Gentle yet makes me feel my action.--Scrolling is smooth.--No stuttering or jerkiness--Instant connect when I first got this, and no problems since--Impressed with how natural it feels. Didnt realize how much the wrist and forearm twist to use a standard mouse. With this, the mouse and arm are in a natural alignment--Charging is quick and easy. Comes with cord for charging. I charge it directly through use of my laptop. It can be used as a corded mouse with ease. Can store dongle in the mouse if need be. Has on/off switch. When in the ON position, it will go to sleep when computer shuts down (or after x amount of time when not used), and wake up along with computer. Typical for rechargeable mouse. If this is anything like any other rechargeable mouse I have had, it should hold a charge for a very long time.--Haven't used this for gaming yet as I have it for use on my laptop, but may try it out on my gaming PC. If I like it, I will just buy another. I think it will work out. This is just so comfortable and easy to use.Take a little getting used to, yet at same time feels really natural. Good grip, good responsiveness, all around good experience in the short time I have had it. Your experience may vary in terms of fit, but I think the quality is evident. I will update if I have anything else worth sharing :)EDIT/UPDATE: Seriously love this mouse, and this company is great. They are VERY RESPONSIVE and helpful when I inquired about an issue I had. WOW really good customer service. Rare these days, thank you. Truly, 5 STARS ALL AROUND.

4 stars instead of 3 because, to be fair, this was one of the cheapest upright mice I found.PROS- It feels great in my hand! The soft plastic is nice, and my arm immediately feels less tension in this position.- The forward and back buttons are easy to reach and feel okay- the main L and R mouse buttons are so quiet. Like, SO quiet. It's really satisfying- charged out of the box, and I like that it charges with a cable instead of taking batteries. Charging port is right in front where mouse cord would normally be so it's no problem to charge while you use it.CONS- No adjustable DPI, and the mouse is soo slow. Will be hard to get used to.- The mouse doesn't glide over my mousepad like my other mice do. It just takes more effort to move it. Which is made worse because the DPI is so low, because you really gotta move the mouse across the whole mousepad to click on something on the other side of your screen- Mouse wheel is not horrible, but doesn't feel super amazing either- There is a button on top that is awkward to reach with the thumb- overall doesn't feel expensive. Which is okay because it wasn't expensive. But maybe don't buy if you want a more luxurious feel on the mousepad.I'd say that if a slow DPI isn't a deal-breaker for you, this mouse is very comfortable and a pretty good value. I may end up returning it for a different one that is faster, though.
