NuleaM504 Wired Vertical Mouse, USB Ergonomic Optical Mouse with 4 Adjustable DPI, 11 RGB Backlight Modes, Compatible for Laptop, PC, Desktop, Mac, Grey

If you’re hesitant, because it looks weird, don’t be. By far the most comfortable mouse I’ve used. Super easy to get used to. It’s so natural, I love it. Wired, so no need to worry about batteries. Lights are fun and changeable. Great product!

As an IT professional and avid gamer, I can confidently say I'll never return to a traditional mouse. After struggling with carpal tunnel syndrome, this vertical mouse has been a game-changer. The discomfort and tingling sensations are gone, replaced by incredible comfort.The soft clicks and gentle scroll wheel make for a smooth experience, while the color-changing gradient adds a nice touch. Plus, the high DPI adjustment is a lifesaver when switching between dual monitors.If you want to protect your wrists and avoid carpal tunnel syndrome, I highly recommend making the switch to a vertical mouse—your hands will thank you!

TL;DR For ~$18, it's difficult to get a better wired ergonomic mouse than this. Few cons such as non-programmable buttons, base could be more flared, limited DPI modes, slightly difficult to use forward and back buttons.I have been using the Nulea M504 mouse for over a month after purchasing for $17.99 USD and my appreciation for mouse ergonomics has significantly increased. There is an adjustment period since you most likely would be accustomed to the feel of a traditional mouse, but after that it's smooth sailing. My hands have not felt any tiredness or pain ever since. Plug and play, and you're on your way.The cable is 1.8m long so you have some wiggle room, though if your device is any further, you may want to look at their wireless options.All buttons on the mouse are pre-programmed, with no option to change them. This would be good for the typical user, but hardcore gamers and power users should look elsewhere if adding macros to the buttons is a requirement.The pads on the base of the mouse allows for smooth gliding across flat surfaces, with low friction. Using a mouse mat should be the preferred option to reduce the amount of wear the pads get over time.The textured grip is soft to the touch and comfortable in the hand. Some may find their hand slipping at first, but I have gotten accustomed to the feel and in less than a month I don't experience that anymore. One change I would like to see is more of a flared base where the hand can sit without falling onto the surface the mouse is resting upon.The scroll wheel is on the higher end in terms of quality and it is easy to use. Made of metal, it feels sturdy, yet it strikes a decent middle ground with the sensitivity and precision of each up or down movement.Just below the scroll wheel is the DPI button, which has 4 options: 1000, 1600, 2400 and 3200 DPI. As I was not able to get the perfect option with just these, I resorted to also changing the mouse sensitivity within the operating system.The left and mouse buttons are easy to click and I had no problem with the amount of pressure needed to activate them. On the opposite side of the mouse you have two more buttons: the top/left one for going forward such as going to the next page in the browser, and the bottom/right one for going back. I have not found myself using these too often, but that is due to being too accustomed to dragging the pointer and clicking the back/forward button on the screen, as well as the buttons being slightly more cumbersome to use compared to the previous method.Reaching your thumb across to the silver button on top and clicking allows you to cycle through 11 different RGB modes, which includes both static and dynamic lighting. At any point in time you can press and hold the same button for roughly 3 seconds to turn off the RGB lighting completely. One small note is this mouse does not have the ability to remember the setting you prefer, so you will have to adjust it accordingly after you power down the PC or switch to using it with another device.

The Nulea M504 is my third type of ergonomic mouse I've used (I've also used the wired Anker Vertical mouse and the wireless Cherry MW4500).What I like:+ I LOVE the RGB. It looks nice and there are a lot of modes to choose from. As others have said, you can disable the RGB as well by long-pressing the light button, which is super helpful if you're using the mouse with a computer that has USB ports that are constantly powered (as mine are) or if you plan to use it at work.+ The scroll wheel FEELS significantly higher in quality than the two aforementioned mice, especially when clicked. It's by far the widest of the three ergonomic mice I've used. Scroll wheels tend to be the first point of failure in mice for me, so we'll how long it actually lasts.+ All buttons have a nice tactile feel and aren't too noisy.+ The mouse is light and easy to use. About the same weight as the Anker, but significantly lighter than the Cherry.+ The mouse curves out slightly at the sides, giving your arm a little bit of support. The Cherry does this too, but the Anker does not.What I don't like:- The backwards/forward buttons are almost flat against the side of the mouse, making them a bit difficult to find with your thumb sometimes (definitely the hardest to locate among the three ergonomic mice I've used).- The mice buttons are only rated for three million clicks; this is on the lower end for durability, I believe. As somebody who uses their mouse a TON for work, we will see how long it holds up. For me, if I get a year and a half or more out of a mouse before the left/right click buttons fail, I'm happy. The mouse is warranted for 18 months, but Nulea looks like a new company and time will tell how good their customer support is.Other things to note:* This mouse is definitely on the smaller side among ergonomic mice. I measured my hand as somewhere around 7 1/2 inches and the front of my index/middle fingers are almost passing the left & right click buttons. On the Anker and Cherry, those fingers rest comfortably on those buttons. I've attached a photo showing the size difference between the Nulea and Cherry.

Due to my work, I'm required to use a wired mouse. I can tell you that this is the best wired ergonomic mouse I have ever had. I love the design, it is very comfortable and you can choose from different LED light color settings. Excellent product.

UPDATE: Changed my 3 star review to a 5 star. All I did was leave this review and I was sent a new mouse. This one works perfect. Now I can see how great the scroll wheel works. I actually never stopped using the other mouse as I really enjoy having the vertical mouse and it fits really good in my hand. I've switched it out now and everything is awesome.I love the mouse overall. Feels really good in your hand, easy control, moves amazing. However, after a month the scroll wheel stopped working. I am moving the wheel and the page will sometimes move but for the most part, get stuck. Essentially I now have a mouse with no scroll wheel.
