J-Tech Digital Wired Ergonomic Vertical USB Mouse with Adjustable Sensitivity (600/1000/1600 DPI), Scroll Endurance, Removable Palm Rest & Thumb Buttons [V628]

I do have to say that this is my impression immediately after having opened the J-Tech Digital V628 (Gen 2) Vertical Mouse. I went from an Anker Ergonomic mouse, which wasn't bad. Although, I do have to say that this mouse is definitely an improvement and an upgrade. It is better designed and ergonomically more comfortable. I believe my home/study desktop is complete with this mouse. I am very pleased with my initial impression and will keep my eye out on what J-Tech develops next for their vertical mouse. Excellent experience so far!I'll write and updated review as time goes on, but for now I'm satisfied.Update after a day of use (3/21/2018): I will say that this mouse will take some getting use to. At times it feels closer to a joystick than a mouse. It is very much comfortable for my hands, which are between medium and large hands. I can see this mouse potentially being a problem for someone with very small hands or extremely large hands.This has been mentioned in another review here on Amazon, but the precision of the mouse is difficult to get use to. I'm getting the hang of it, but it is not something that will happen overnight. Some other reviewers mentioned how the mouse does not have precision, which led me to believe that the optics on the mouse itself may be of lower quality. This is not true. I find that it is the fact that you have to move your arm in a different way to get the precise movement that you intend. So there's a learning curve to say the least.But overall, my impression is that this is a high quality product that has high value for its price point. The next vertical mouse that I would consider is more than two times the cost of this.Also, the LED lights are a very nice touch. I do have to say that this Gen 2 version is much more attractive than the previous generation. This mouse honestly looks like a piece of art on my desk. Very unique looking and has very smooth contours that are appealing in a modern contemporary way.One other point of consideration is the Forward/Back buttons by the thumb rest. These are placed in a way that makes it extremely easy to trigger when using the mouse, but I have noticed that it is easy to press these buttons by mistake when grabbing the mouse to use. This is another part of the learning curve. When browsing websites it is very easy to use these Forward/Back buttons in the sense that it is lightning fast to trigger, but will require getting use to their placement.Still satisfied and hoping that there won't be any negative aspects to this mouse with future use.Update 4/15/2018After using this vertical mouse just under a month, I have nothing, but a positive experience to report.I have become accustomed to the design and my hand naturally grabs the mouse now. It was not as easy when first using for the first week or so. Now I am even able to use the mouse without a full on grab. I can just use my index finger, middle finger, and thumb to do a quick movement of the cursor. This greatly adds usability for causal use. When I'm fully engaged in what I'm doing on the computer I will use a full on hand grab, which is very comfortable to use indeed.The backward/forward buttons by the thumb position looked very cool in the photos of the J-Tech mouse, but it really is effective in use. When first getting use to the mouse, I would grab the mouse and inadvertently press one of the backward or forward buttons. This since has stopped after almost a month of use.I use this mouse on the right side of my Microsoft 4000 ergonomic keyboard and a Logitech T650 touchpad on the left. I have become accustomed to this setup and I am glad I purchased this V-Tech mouse. I feel that my setup is complete now.Ultimately, I would say that this vertical mouse has a learning curve. If you are motivated to gain the benefits of its ergonomic design then I believe anyone can learn to use it within a month. But I do understand the few reviews that mention how it is nothing special or that it has an awkward design. It definitely is not for the average user. But for those that have a desire to move beyond an ordinary engagement with their work on a PC, this will definitely move you to the next level.

I really like this ergonomic mouse. The mouse I'm replacing was not as high as this one, so I'll need to get used to the angle, but it is much more comfortable than the one I currently use. I love the gradient rainbow colors. I don't like using the palm rest because I've never used one before; it feels awkward. It connects with magnets, making it easy to add and remove. It will live in my drawer, but for those who like palm rests, it is a nice one. I highly recommend this mouse. The scroll wheel is easy to use, the angle is comfortable, the right and left clicks are easy to use, and it glides smoothly on a mouse pad. Great product!

I got this mouse when it was on sale for ~$22 and the first thing I noticed was that it's a bit large. I've been told I have slightly small hands (approx. 7 inches or 18 cm from bottom of my palm to the tip of my middle finger), and the mouse is a touch too big for me for it to be fully comfortable. I can still use it, but it takes some stretching to use the scroll wheel.The palm rest is attached with 3 small magnets at the bottom of the mouse. It drags smoothly, but it's not a cushion. I think it's just something to help prevent the side of your hand from dragging along a desk/surface. I haven't used the mouse for long, but I'm mildly worried that palm rest will just come off as I'm using it because of how easy it is to come off.I do enjoy the overall feel of the mouse compared to the standard regular mouses. I also like the RBG lights as a simply cosmetic thing to make it appear fancy. I do not have an RBG gaming keyboard, but I assume it would match well with one.So far, and easy 4/5 stars. I only deduct one star simply because it's larger than expected and the slight disappointment in the lack of cushion in the palm rest. If there are any changes in my rating or thoughts, I'll give an update.Update:It's been a little under 4 weeks, and I have been using this mouse for about 8-12 hours every workday. I turn the mouse off during the night and weekends to conserve battery. There is definitely a learning curve, and since my hands are on the smaller size, I needed to find the right grip so that my arm didn't hurt after a lot of usage.I charged it fully when I first got it, and it just now ran out of battery. The palm rest is kinda heavy to drag around, so I'll sometimes take it off. Although, it is nice to have since the side of my hand doesn't drag across the desk. Essentially, my rating stays the same just because the palm rest is a bit heavy.

I've tried about a dozen mouses (mice?) to try to relieve my wrist pain. I wore a wrist brace, but the pain just migrated up to my elbow and shoulder. Within a few hours of using this mouse, the pain is GONE. I'm blown away. The wrist-rest means I can actually rest my hand instead of holding it "up in the air" like some other ergonomic mice. The size is perfect, not too big to where I can't reach the buttons or so small that it's hard to hold. The lights are a nice touch. Not overly bright. And it's rechargable. If I had just one ask, it'd be for it to work without the dongle, via bluetooth. I only have 2 ports and 1 is taken up by my keyboard dongle, so I'm left with no extra port. (I know I could get a splitter. I don't want to.) But for my pain to be gone, 5 stars. I'm buying another one to leave at work, and returning all the others I ordered.For reference, I'm a woman, size 8 shoes (so you can extrapolate the approximate size of my hands). The angle on this isn't quite 90, maybe 80? It's the most upright of all the mice I've tried.
