UtechSmartVenus 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 HoursRecycled Claim Standard Blended

I bought this mouse four years ago, seeking a cheap replacement for a Razer MMO mouse that had failed. It's July 2025 now, and I bought it in July 2021. It's the best, most versatile mouse I've ever owned! Normally you get what you pay for, but I'm here to tell you, this inexpensive mouse easily outperforms $120+ mice, and outlasts them, too. The picture in this review was taken today. As you can see, it's still in great shape.Durability: I have used this mouse almost every single day since I bought it, for both work and gaming, and it's been absolutely bulletproof. Keep in mind that bought this mouse FOUR YEARS AGO, and it still works just as well as the day I took it out of the box. It's the single most reliable computer peripheral I've ever owned.Customizability: It comes with an easy to use companion app to program what the buttons do, and every button is customizable in a variety of different ways. Plus, you can save multiple button configurations to the NVRAM on the mouse so that if you don't want to run the app, you can close it during gaming sessions. The colors and brightness are also fully customizable as well. It does NOT have have customizable weights, but for me it has just the right amount of heft. (I dislike lightweight mice anyhow, to me they feel really cheap and I find them harder to control, but that's just a personal preference.)DPI control: Also customizable through the app, you can choose the sensitivity of each DPI setting. There are five levels, all displayed on the mouse LEDs, showing 0-4 lights to show what level you are on. Not only are these settings customizable, but you can have different sensitivity levels per profile. To be honest I don't use this feature much, except in FPS games when I want to lower sensitivity to line up a snipe or something, but it's neat to have.Wireless / Wired: I love that it works both wired or wireless. It changes on the fly in under a second so if you forget to plug it in for a week and the battery happens to give out in the middle of a gaming session, just plug the USB in and it's back up and running instantly. Plus, there's no noticeable input lag in either mode.Size / Comfort: It fits my hand perfectly, but I think it might be a little large for someone with very small hands, so keep that in mind. It's got a very wide feel to the grip, with a little shelf for your left thumb to sit on, and a gentle groove for your ring finger to rest in which ends up feeling like a weird hybrid of a claw grip and a palm grip. (Claw, because of the way the mouse has a groove for all your fingers, and palm, because it's wide and easily controllable by moving your whole hand palm grip style, versus using your fingertips. The mouse fits your hand like a glove to a certain extent, because it's not flat, it's contoured for each of your fingers and even the gap between the third knucke of your forefinger and middle finger.Other considerations: The thumb buttons require a little bit (but not too much) force to actuate, so I haven't ever pushed one by mistake. The extra button that sits just to the left of the left click button is also fully customizable and that's a really fantastic feature to have, because it gives you four items you can click with your fingers, and twelve different items you can click with your thumb, for a total of sixteen functions. I've also gotten a mouse that looks almost exactly this one that's from RedDragon, so my guess is that this hardware might be made by a third party and the licensed to multiple companies. The RedDragon mouse only lasted me a year, though, while this one is in for the long haul.Long story short, if you need a mouse with a lot of thumb buttons, get this one. Not only is it less expensive than competing high-end MMO-style mice from Razer, Corsair, SteelSeries, and Logitech (I've bought 'em all!), it's better, too.

This mouse is well worth the price. The buttons are just the right size to click with your thumb and the pressure needed to press them make them easy enough to press in tense moments while also making mistakes fairly rare. I use the back of my thumb to press the last column and this even works pretty well. The rapid fire button feels quite nice to press as well. The scroll wheel is segmented but also smooth.Minor complaints include the fact that I am not a huge fan of the sandpaper feel on the left/right buttons and on the edge. In particular, I found that my ring/pinky fingers started to feel chafed by it when first using it, though I believe use of the device quickly wore it in and I no longer get this feeling. I do also wish the thumb rest was extended a bit further out from the mouse. I do not use it that often, but it is not really wide enough to fit the entire thumb without it hanging off the edge.I love that the mouse is wireless, as I could never get used to the cord snag that occurs with wired models, though it can also be used with a wire if that is your preference. The battery life is superb. I can forget to charge it for days at a time and it will still have juice. The sleep mode activates pretty quickly after not using the mouse for a period of time and will automatically awaken after any movement/button presses and will register said input.The two DPI buttons are placed in a nice spot and there are four red lights, or the absence of light, which indicate five different profiles. These are set to 1000/2000/4000/8000/16000 by default, but you can set them to whatever your preference is. As I find any lights on my mouse/keyboard distracting, I set my preferred DPI on the lowest profile. That said, the RGB lights on the mouse are great. The thumb buttons look particularly cool when it is shining through them. If you want to show off a cool new mouse, this is the one for you.The program for this mouse is also pretty great and easy to understand. The default profile for the thumb buttons sets them to 1-0 on the number row and -/+ on the number pad. I'm not sure why they decided to use the numpad rather than the number row for the last two, as I have played games which contain item slots on the latter number row keys, though they are easily remappable in the program or in-game. The program allows for importing/exporting profiles, which is necessary if using more than two. The profile switch button on the bottom can cycle between the default, which is itself remappable, and an imported profile. The program also allows the user to design macros which is very convenient for the sake of productivity.For gaming, the number row mapping already makes perfect sense for many games. Even though I do not really play MMO games, I found that being able to swap weapons in GTA and items/shouts in Skyrim with the touch of a button was quite an improvement over using the number row, which takes fingers that could be pressing other keys and has an inconveniently placed second half for the left hand to reach. Of course, you can feel free to map it to whichever buttons you want.I also personally use this for video editing and general productivity shortcuts on my PC and I can report that it is excellent for both. My left hand has to move around far less than what it used to, and overall things feel more balanced. Overall extremely pleased with my decision to purchase this mouse and recommend it to anyone who wants a versatile instrument for any of a multitude of computing needs.EDIT: I have dropped this review to four stars because of an issue with the scroll wheel. After having the mouse on for some time the scroll wheel takes two notches to start scrolling in the opposite direction (for instance, if I am scrolling down and I try to scroll up the first notch on the wheel that is scrolled up will do nothing). If I turn the mouse off and then on again it will return to normal, but will, in time, begin to act up again. It is rather minor, but is quite annoying. And I can see this being a detriment in games. I have reached out to Utech's support and have not gotten a response. I am trying again. If my issue is resolved I will return the review to five stars.EDIT: I managed to get in contact with them through the email for the gift inside the box. They were very nice and sent me a new one. While the second one was on the way, my original somehow started working again. I can only surmise that it has something to do with being kept on for a long enough period of time, rather than being turned off and on again after acting up. Anyhow, I am pleased that it has started working again and that I now have a backup in case it messes up once more, and am now raising it back to five stars!
