UtechSmart Venus Pro RGB Wireless MMO Gaming Mouse, 16,000 DPI Optical Sensor, 2.4 GHz Transmission Technology, Ergonomic Design, 16M Chroma RGB Lighting, 16 programmable Buttons, Up to 70 Hours

This is a great mouse for the price you pay. I purchased this mouse in mid-2023 and it's starting to die on me. After 18 months, the battery still holds good charge (gets to 70% after a longer gaming session with RGB on but it does die quickly afterwards), lights work, unfortunately the left and right buttons are wearing out. I use it for gaming so you can guess that the click-count on those is high. Previously I've owned much more expensive logitechs which have lasted me longer but they also had less bells and whistles. That's your trade-off essentially.As far as the size of the mouse and the grip goes, I found it comfortable. It's what I would call an average sized mouse and it's a nice grip. I have a hard time reaching the 1,2,3 buttons with my thumb and 4,5,6 are not a great ergonomic reach either but i don't need that many buttons. The software it comes with has a good amount of control and customization options and you can assign lesser used features to those buttons if you use macros or what not.

Disclaimer: - I bought this mouse myself. I did not receive it as any part of a promotion, therefore the below is entirely my own thoughts & opinion.The 1st thing I noticed was the texture on the outer layer of the mouse. For lack of a better term, it's "gritty" and it's frankly a game changer. Not that your hand ever gets so sweaty where a smooth mouse causes an issue, (or perhaps it does) but it allowed for light grip that still allowed total control. This is the first mouse I've owned that has had this type of outer layer and like most of you here, I've owned a LOT of different mice over the years.For me, one of the biggest selling points was the ability for it to be used either tethered to your PC (wired) which charges the onboard battery whilst in use or completely wireless. To switch to wired or wireless there is a selector switch on the bottom side of the mouse, just to the left of the sensor. You can also turn the RGB's on from this same location should you want to.The 12 programable buttons on the side will come in handy when extra rebindable keys are needed, especially for RPG's. They have a soft feel when pressed and are silent, vs. the regular "clicking" sound the 2 primary mouse buttons make. This may be why some people thought they felt "mushy" when they were just silent?Last but not least, the mouse's sensor is absolutely smooth as silk. I immediately noticed a difference over my current mouse, which is from a major brand (I'll not bash them publicly and so will not use their name) and cost more than the Venus Pro but isn't even in the same league as it. The difference is that pronounced, though I'll most likely still suck in-game lol!The mouse came with a USB-C cable for charging and wired use, along with the USB dongle for wireless use. It also comes with an "flat" USB thumb drive that you pop-out of a credit card shaped holder and insert into a USB port on your PC or laptop. Keep in mind that It does not look like your standard USB drive, but more like a long & narrow MicroSD with the "contact" facing up so you might need to try out which way it inserts into the USB slot on your end. Once it does, it'll automatically take you to the page where you can download and install the software where you can then change the RGB colors, custom configure the keys, change the polling rate and configure the 5 levels of DPI settings. (100 DPI to 16,000 DPI which is switched to on-the-fly by the up & down arrows just below the scroll wheel. It's nice as each press turns a light on next to the up & down arrow showing you which DPI the mouse is currently set at.) The software itself is both intuitive and so easy to navigate.Time will of course be the ultimate judge, but so far, it's proving itself to be an excellent mouse!

The RGB quality is ok, and is fairly bright even on the lowest notch. I intend to use it primarily with no lighting, so a helpful and appreciated feature on this mouse is the 3-position on/off/on switch - there's ON (with LED), OFF, and ON (without LED).You can customize the light color using full-range RGB (0..255 each for red, green, blue) for a supposed 16 million-something colors - but I doubt you'd be able to actually discern more than a couple hundred colors. The difference between dark & light shades is a very minor brightness change. For example, comparing blue=25 vs blue=255 should be like comparing a stick candle vs LED brightness -- but it's more like comparing a flashlight w/ dying batteries vs the same flashlight w/ new batteries.The movement speed of the mouse can be toggled between 5 customizable DPI levels, which you can set from 100 (which is basically "drag the mouse across your whole desk to move half an inch") to 16000 (aka "put your hand on the mouse to teleport the cursor across the screen"). When the software is running, you get a popup that reminds you which DPI level you've just changed to. You can also see the current DPI preset based on the number of red lights that are on, below the middle button.One very random and strange limitation is that the mouse refuses to work on jeans. It works 100% fine on a t-shirt and a sofa cover, as well as multiple different patterned & solid-color desk surfaces. But on my jeans it just doesn't move at all.A few random negatives for this mouse that collectively drop it to 4 stars:- The requirement to use the included wireless adapter, rather than supporting standard Bluetooth, means you can't see the battery status natively like you would if it were connected via bluetooth. The lack of a charging light on the mouse itself means you are limited to checking the battery level from within the UTech Venus software.- The manual explicitly recommends to NOT charge this via wall adapter because of potential damage to the mouse's internals... that's not inspiring a whole lot of confidence in the mouse's circuitry.- The software's UI does not scale for 4K, so you may need to break out the magnifier, or get up real close to the screen, to be able to read the microscopic text on a 4K display.Neutral observations:| The DPI switch buttons, that will probably see very little use, have a nice mechanical click to them; meanwhile, the side buttons that will see far more usage have a soft tactile bump - personally I would have preferred these switches being flipped the other way around, with the side keys having the nice crispy click.| Something that will take getting used to is navigating the side buttons without continually re-centering your thumb. The tactile ridge on the #5 and #8 keys is a little too close to the edge of the buttons to be useful. You can barely even tell the ridges are there cause they just feel like the edge of the button. Muscle memory will probably compensate for this with more usage, but it's still worth mentioning.
