AUTLEY Wireless Vertical Mouse, 2.4G Optical Ergonomic Mouse for Laptop, Computer, MacBook, Adjustable DPI 800/1200/1600, Black

It's comfortable and easy to use, for the most part. All of the buttons are easy to press, EXCEPT for the forward button; something about the angle your thumb needs to press it at makes it nearly impossible to use. Pressing the button head on confirms that it's pretty much identical to the back button, aside from it's slightly different placement of course. For me to press it properly, I have to push it UP a little instead of inwards, which requires me to move my pointer finger off the Left Mouse Button while pressing it. I would probably change the way this button works to make it easier to press at an angle in future revisions of the mouse. Aside from that one button, you won't have any difficulty pressing any of the other buttons at all, despite the 80 degree angle of the mouse. They are surprisingly easy to press and responsive to use. I really enjoy clicking and scrolling.Speaking of the angle, I appreciate how extreme it is at 80 degrees, though something tells me that I would prefer a more extreme angle, myself. Something about being between 45 and 90 degrees makes it feel a bit weird, but I think it might be just a matter of getting used to it. And while I'm more used to using a normal, 0 degree mouse, this is definitely more comfortable.The mouse is surprisingly precise. It's not super-accurate or anything, but you can comfortably use it with mouse acceleration (called "enhance pointer precision" in Windows settings) turned off, which is something you cannot say about a lot of cheaper, non-gaming mice on the market. You can use it for pretty much anything you want besides precise image editing (which you should probably be using a pen tablet for) and modern FPS gaming (which you should probably use a gaming mouse for; I recommend the Logitech G305 for most people). So when you're not doing either of those things, this mouse really helps cut down on the strain you put on your arm.The wireless dongle tucks in nicely in a spot under the battery door when you are not using it, or when you want to move it around. The mouse includes the all important on/off switch for those occasions as well. Overall, this mouse seems solidly built. Shaking the mouse, the only thing I hear is a tiny bit of sensor rattle, but because this mouse isn't meant for serious image editing or gaming that's not really much of an issue. I will update the review in the future if it ever decides to break on me, but I doubt it will.

I'm not going to speak on ergonomics, but this did help mitigate some of my issues with the nerves in my right arm.That said, I experienced a problem with these mice. I had another one, and after I replaced the battery it started behaving very erratically and kept cutting out. This new one did the same thing after the battery finally 'died'.After thinking about it, since these mice use a diode to produce the light for the optical sensor, they can under the right conditions be very sensitive to small changes in voltage. I checked a few brand new batteries with my multimeter, the one I had issues with was 1.528 volts (nowhere near dead, very in-spec for a battery). I found one that produced 1.6 volts, swapped it out, and it /seems/ to be working far better so far.This is just poor design. Either the manufacturer needs to select a different emitter, or you need to switch to two triple A batteries to increase input voltage so you can regulate it down. Something, anything. It's far too sensitive at the 1.5V to 1.6V level. An emitter change would probably be cheaper, assuming you can get better I-V characteristics. You should NOT have new batteries failing to work due to hypersensitivity in the nominal new cell voltage range. Period.That said, I don't have an issue with the build quality in any other way. I dislike having no indicator for the DPI selection, as that is extremely useful for when I bump it as on my Thermaltake TT mouse.

This is probably the most comfortable mouse I own, but without instructions it's taken me forever to figure out how to change the DPI. I put the Autley away and tried several other mice in the interim, because the tracking on this thing was just too slow. Finally I randomly pushed buttons till I found the one that fixed the problem (the small one behind the scroll wheel), and voila! it now works the way I want it to. This is a much larger vertical mouse than others I've used, but I have rather large hands for a woman and it's the best fit for me.

My first ergonomic mouse was the Anker 2.4G (https://www.amazon.com/Anker-Wireless-Vertical-Ergonomic-Optical/dp/B00BIFNTMC/ref=psdc_11036491_t1_B07VP1KKJ6) but over time the sensor was laggy, not smooth and it used two AAA batteries (super annoying) so I decided to upgrade to this bad boy.Compared to the Anker 2.4G...PROS:-Price point-Smoother sensor-Uses one AA Battery-A combination of matte and shiny textures-Firm mouse clicks and middle roller is smooth.CONS:-It's a lot wider compared to the Anker 2.4G --not meant for people with smaller hands. Feels like I'm handling a small mug. Whereas the Anker 2.4G has a slimmer built and more grasp support for the thumbs. It took about a week to get use to the widthThe overall feel of this mouse is similar to a joystick due to the width and bulkiness. Once you get use to it, it feels fine. It is a personal preference.

One thing right out of the gate that I know a bunch of reviewers pointed out that I can't stress enough... The forward and back buttons are absolute trash. Mushy, the exact opposite of a tactile feel. I'll give the scroll wheel a pass, it works, but it is not very satisfying to use. There is little resistance, and I find myself scrolling to far for a majority of pages. As far as the ergonomics go, I'll have to sit on it for a while as this is the first mouse I've tried with this style. So why 4 stars? The price! Got this sucker on Cyber Monday. If you can score it under $10, grab this mouse. I'll update the review as I use it more.
