The J-Tech Digital V628X is a very uniquely designed vertical mouse. It has an adjustment to allow you to change the angle, but unfortunately, our unit didn't seem to tighten enough and the angle didn't stick. It has a large base that looks like a dock but is connected to the mouse at all times; this makes the mouse very bulky and heavy and increases the drag on your desk. While the CPI is adjustable, unfortunately, it's very inaccurate and has among the highest CPI errors we've tested so far.

Our Verdict

5.8 Mixed Usage

The J-Tech Digital V628X is inadequate for mixed usage. This mouse is designed for day-to-day or office use, and its heavy and bulky body makes it almost impossible to travel with. Its inaccurate sensor performance also means it isn't recommended for gaming. On the upside, its vertical design should reduce wrist strain when using it for extended periods.

See our Mixed Usage recommendations
6.1 Office/Multimedia

The J-Tech Digital V628X is a mediocre office mouse. While its vertical design should help reduce wrist strain over long periods, unfortunately, its buttons are a little difficult to reach comfortably. It also has an angle adjustment, but it didn't tighten enough to work properly. The mouse feels poorly built overall, and it's too big for people with small hands to use well.

2.6 Travel

The J-Tech Digital V628X isn't recommended for travel. It's a very large and heavy mouse that likely won't fit in any laptop bags.

5.9 Video Games (FPS)

The J-Tech Digital V628X is inadequate for FPS gaming. While it has an adjustable CPI, its CPI error rate is so high that it's very inconsistent and inaccurate. It's also a very heavy mouse that will make it difficult to move around quickly while gaming. The mouse can only be used in palm or claw grip for anyone except those with small hands.

See our Video Games (FPS) recommendations
6.9 Video Games (MMO)

The J-Tech Digital V628X is an okay option for MMO games since all of its buttons are programmable, and it's decently comfortable to use for long periods. Unfortunately, it feels poorly made and its sensor performance is very inconsistent. This mouse can only be used in palm or claw grip and isn't recommended for people with small hands.

3.8 Ultra-Light Gaming

This is one of the heaviest mice that we've tested so far and isn't appropriate for ultra-light gaming.

Style

The J-Tech Digital V628X has a very unique design that's different than most vertical mice due to its large bottom that looks like a dock but is connected to the mouse. The scroll wheel is a large disc that can be controlled from either side of the mouse. There's RGB lighting on the scroll wheel and under the two side buttons on the left side.

Due to its very large and heavy body, this mouse is meant to stay on your desk and isn't at all portable.

Build Quality

Despite being very heavy, this mouse feels very cheap and not at all solid. The plastic is cheap and the seams between the different sections can be separated easily. The cable of our unit was already frayed when we took it out of the box, and the scroll wheel is very wobbly.

The J-Tech Digital V628X is a decently comfortable mouse. The side buttons are a bit too low to reach comfortably, and the scroll wheel is more comfortable to use with your thumb but feels much more stable when using your index finger. On the upside, its vertical design should reduce strain on your wrist if you use your mouse all day, though we don't currently test this. While it has an adjustment to change the angle of the mouse, unfortunately, it doesn't hold well so even when it's tightened, the angle still moves a bit, making this feature less useful than it could be.

The J-Tech Digital V628X isn't recommended for small hands with palm grip, as it's difficult to reach the scroll wheel.

The J-Tech Digital C628X's cable is disappointing. It has lots of kinks from packaging, and our unit's cable was frayed when we first unboxed the mouse.

The sensor is off-center which makes its cursor movement slightly awkward, especially if you move the mouse using your wrist as opposed to your elbow.

The J-Tech Digital V628X's click latency is surprisingly great and most people shouldn't notice any delay.

While performance is good on paper, the very high CPI error means that it's incredibly unstable and results in a very poor performance experience. The polling rate isn't adjustable, and the sensor snaps and spinouts a lot.

The mouse wheel is mediocre. It's quite soft and is fairly unstable, especially if you use your thumb. While it's more stable if you use your index finger, it's more uncomfortable and awkward to use it this way.

There was no software available for this specific model, but the product page points you to the M618X Driver, so it seems the company repurposed the software from another mouse without changing the name. The software allows you to adjust your CPI, though it's not accurate.

The software for this mouse only works on Windows, but luckily, the mouse has on-board memory so you can make changes on a Windows PC and move your mouse over to a Mac and keep its settings.

Compared to other mice

The J-Tech Digital V628X is a uniquely designed vertical mouse that has a large base attached to the bottom of the mouse and has a different look than the Anker Vertical Mouse or the Logitech MX Vertical. While it's designed to have an adjustable angle, unfortunately, we found the adjustments didn't work well. See our recommendations for the best wired mouse or the best mouse overall.
