Anker2.4G Wireless Vertical Ergonomic Optical Mouse, 800 / 1200 /1600DPI, 5 Buttons - BlackECOLOGO

Works Great - very comfortable. I have a few issues with my right hand, need carpal tunnel surgery and had broken my wrist playing football over 30 years ago and am pretty sure arthritis is involved now so there is a lot going on there. A traditional mouse was getting more and more uncomfortable, especially with the wrist action involved. This mouse has helped alleviate alot of the discomfort. 👍 Still getting used to the movement and precision needed for some tasks but it is a good mouse !!

I bought this mouse because I was having pain in my arm from using a regular mouse. The pain in my arm has completely gone away. There is a little bit of a learning curve just because your hand is in a different position. This mouse allows your hand and arm to be in a more natural position so there is no strain on your arm. The purchase arrived quickly and on the date it was promised.

Great mouse. Purchased two. Rubber grip separates from the scroll wheel rendering it useless after a year or two. Great ergonomics, great clicks, needs a better scroll wheel.

Always a good brand. I always choose anker if I have a choice. It felt weird at first but I’m getting used to it. I ctrl-copy and ctrl-paste all day and this helps my wrist from cramping. It took a couple days to get used to a new hand position but it’s worth it so far.

Nice mouse, but uses too much batteryAnker 2.4G Wireless Vertical Ergonomic Optical MouseI liked this mouse, until the AAA fresh batteries I put in it less than 2 months ago when I first got it just died.What I like:Other than the terrible battery life, it's mostly a nice mouse, for the price. I got it on a lightning deal for $15, 2 months ago. I had been wanting to try this style of mouse for a while, and landed on this one. It took a little bit of getting used to, but that was mostly learning which surfaces it tracks best on. (I use my computer from my bed, so the mouse is frequently used on fabric. And every fabric tracks differently with the mouse) I was coming from a Logitech Marathon wireless mouse. And they both track differently on different materials. Though my Marathon mouse is 5 or 6 years old, so it doesn't work as well as it used to. This Anker mouse is lighter than the Logitech mouse, but some of that could be down to AA batteries vs AAA batteries. The lighter weight probably helps with fatigue, just a bit. But it depends on how you use your mouse, and what weight you prefer.This style does seem to help with hand and wrist fatigue from using a mouse. I'm noticing more wrist pain now, while using my old mouse as a backup, than I realized I would. With the Anker mouse, I didn't really notice the lack of pain as much, so I didn't realize just how much of a difference it made till switching back. (out of fresh batteries, and the current set just died)What I don't like:The scroll wheel. On the Marathon mouse, it has a free spinning scroll wheel, which makes scrolling a breeze. (none of those nasty finger cramps from scrolling for days) This Anker mouse has the traditional style. But also, for side to side scrolling, it will only scroll to the right. There is no movement to the left. So I tend to do a lot of clicking the scroll (for the on screen scroll control) wheel to scroll through pages, though that isn't available for everything.And the afore mentioned battery life. I don't understand why it sucks down the battery power so quickly. The AAA fresh batteries I put in it less than 2 months ago, when I first got it, just died. At this rate, this is going to be an expensive, and quite wasteful, mouse, using a dozen batteries each year. (if I were to buy rechargeable batteries, it would cost me around $30 for batteries and a charger) And the need for multiple batteries increases the chance you will have a dead mouse and no batteries. (I'm out of fresh batteries right now, so had to go back to my old mouse just to use my computer today)The range also isn't as good as my old Marathon mouse. I've had issues with the signals reaching the computer from just a couple fee away when part of my vintage wood desk was in between. I'm not sure if it was just the wood that was the problem, or something else. But just beware if you plan on using this if your computer (or a USB hub) isn't right there on top of the desk. (My marathon mouse I've never had a problem with. It will reach from the next room, farther than you can see, really.)So, would I buy this again... Probably not. But if you are looking for a cheap vertical mouse, it might be a good fit. Just don't expect it to be great... And stock up on AAA batteries, or get rechargables.UPDATE 6/26/21Anker emailed me a day or two after my initial review. And offered to replace the mouse with either a new wireless, or the wired version of the same style. And they assured me that batteries should last longer than 2 months. Since I don’t really want to risk having to still replace a ton of batteries, they sent me a new wired mouse. Even with a couple emails back and forth, I think I still got the replacement, completely free, within a week of my review. (I just haven’t had a chance to use the new, wired one yet, because my computer got fried from a power surge during a thunderstorm a couple weeks ago. But I’m sure it will be fine.)I shouldn’t have been surprised, because I have had nothing but positive experiences with Anker customer service when I have ever had any issues with a product in the past. Anker customer service is 5 star. So if you do have an issue, they really do stand behind their products, and their warranties really do mean something! That being said, I’m still not sure how long a pair of AAA batteries is supposed to last in this mouse, so I’m not sure if I would want to buy this again. I think I just go at spoiled using a mouse that was years between battery changes...(I didn’t change my star rating, or my original review though. Despite great customer service, this is my honest assessment of my experience with the product I bought. I probably just got a lemon. But that’s how it goes.)

I'm overall satisfied with this mouse, especially at this price. Other vertical mice can cost over $100. It does exactly what I need it to do, but I had to add a wrist rest to really stop the pain and discomfort that I've been experiencing when using a mouse. Doesn't come with the 2 AAA batteries you need to power it.

This mouse is ALMOST perfect. It's not a complete replacement for the Logitech one I had, but it's working in the meantime.The one thing I do find a bit odd is the clicking responsiveness. It is a bit difficult to get it to double-click at times, but that just might be my hand issues more than anything.Otherwise, the mouse is great!
