Nulea M504 Wired Vertical Mouse, USB Optical Ergonomic Mouse Wired with 4 Adjustable DPI, 11 RGB Backlight Modes, Compatible for Laptop, PC, Deskt...

Just what I wanted. Great feel, the right features and awesome price. The cool led lighting is a bonus!

I've had this for over a year and it's been awesome! It took about a month to get used to its super lightweight, but that's my only criticism. I have considered taking it apart and adding weights but have not tried to yet. It fits my hand so well compared to Logitech's Ergo mouse. It's a little thicker in the finger area and more supportive to my palm. For reference, I'm 6 feet tall and most of my clients who are close to the same height also prefer this over the Logitech as well.

I'm on a computer 8 or more hours a day and was suffering from carpal tunnel pain. I ordered this new mouse and almost immediately I could tell a difference. It is ergonomic, and easy to grip and use. I also like that it is wired and I don't have to worry about batteries or Bluetooth connection. Excellent price and the lights make it fun. I would recommend to anyone who spends alot of time on their computer.

The design is so comfortable, no more wrist strain. Mouse functions nicely, scroll wheel is smooth and works much better than my old mouse. The buttons are easy to access. Love the colored lighting and how simple it is to change colors or turn off. I bought a second one for my office.

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.
