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

I bought this back in November 2021 and realized I never reviewed. Well it's July 2025 and the mouse is still going strong! Still works great and looks relatively new. I usually have the RGB lights off but those still work. I haven't had any issues with the mouse since I first started using it. I'm surprised this has lasted almost 4 years since I wasn't expecting much when initially buying it, but I'm still happy. I'll definitely be buying a new one when this one's done. From my experience, I highly recommend!

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.

This seemed like a good idea at the time that I ordered it. I wanted something that would keep my hand in a natural position. Unfortunately, this product, though it appears to be well made is not a good fit for everyone.Initially putting my hand in place on the mouse felt natural, until I started to use it. Then my hand slipped down the side. If I put my finger up on top of the mouse to keep from slipping, then that put my hand in a bent shape which is what I am trying to avoid doing. It comes with a heel rest which needs to be used otherwise the hand rests on the table which gets uncomfortable from the constant movement. Also, one needs to use a wrist rest to keep the hand up so it will be aligned with the buttons.As for the button placement, I liked the way that was designed. Kudos for that and for the wheel placement. But again, with the hand slipping on the mouse there is way too much movement to use the buttons and/or the wheel.The shape of the mouse reminds me of a snail. When the hand is placed on the mouse "properly", then there is a gap between the back of the mouse and the palm of the hand. Thus, one is actually putting that hand in a position of having to "hold" the hand up rather than letting it rest on the mouse. I read somewhere a comment that said the mouse was like a joystick. It loosely is. At least with a joystick one can hold onto it and maneuver the buttons without all the hand movements to hold onto the joystick.I am 5'5" with a medium sized hand. I would say if it weren't for the slippage, this would be the ideal mouse configuration for a slightly smaller hand. I will go back to the old-style ergonomic mouse where the hand can rest on top of it. That is actually the best in my opinion.One last thing is the blue light that is on the mouse. Luckily that can be turned off. When it is on it is very annoying. I don't know why that was put on to begin with. It was a waste of time and more than likely money.Overall if one has a smaller hand this would possibly be a good fit. Otherwise, shop around and be aware that this style will not fit everyone properly.

I bought my 1st one in 2019, I need to order a new one not because it stopped working but because I wore the ridges right off the scrolling wheel! It has kept my wrist pain at a minimum and I'm certainly happy I bought it.
