My DeathAdder 3G had been acting up on me for the past couple years and despite my attempts as resuscitating it (tried using compressed air on click switches as well as doing a 'scotch tape trick' on scroll wheel), the unit finally stopped working. My problems with this mouse at the end of its life were that 1) a click would sometimes register an additional click - making me accidentally open files when I wanted to just select them. This made dragging files around really frustating. 2) The scroll wheel would also randomly insert an upward scroll movement in the middle of a down scroll - which would make viewing webpages and documents a chore.My requirements for a new replacement were that 1) I wanted a mouse with good switches (preferably Omron) to avoid the double click problem. 2) A scroll wheel that would smoothly scroll and was of solid construction to not end up w/ the same scroll problem. 3) A mouse that could entirely turn off its LED lights as I have my desktop in my bedroom and prefer to have no external lights.I ended up trying several off of YT Rocket Ninja's Top 10 Mouse list. Although I do not game very much anymore, I figured a mouse that could survive the rigors of heavy gaming would be of higher quality than other office mice and would thus last longer and provide better feedback. Here are my thoughts on various mice that I tried and the Logitech G Pro which I finally ended up getting. (I tried each mouse for about a month to give me time to form a proper opinion.)Redragon M801 Mammoth - This mouse was the first candidate that I tried based off of Amazon's recommendation list. It had a really nicely textured mouse surface and the clicks were really crisp (Omron switches). The mouse was of a comfortable size for my hand and the cord was a nice braided one. It really was a quality piece and the price was by far the cheapest out of any of these other mice ($28). The software was also really light compared to the Razer Synapse software which seemed to want to update every 2 days. My main problem with this mouse was that you could only turn off the LED lighting to the wheel and dpi switches, and not the giant slash and side trim pieces. I did however find a YouTube tutorial that showed how you could unscrew the assembly through the weight compartment to pull the internal connector to disable the lights but did not want to go with the hassle). For people that don't care about the LED lights and/or on a budget, I would actually give this a 4* recommendation.Logitech G403 Prodigy - The next mouse I tried was the G403 after discovering Rocket Ninja's YouTube page. This was his #1 selected mouse so it was a good next choice. I learned that having the distinctly separate mouse buttons from the chassis aided in the longevity of the click buttons (The DeathAdder 3G had the buttons integrated in the overall shell of the body). Unfortunately, I found the mouse wheel to be much looser than my original DeathAdder as well as the Red Dragon and decided to return this mouse and look for alternatives. (3.5*)Razer DeathAdder Elite - I went with the DeathAdder Elite after my experience with the G403. Being a more expensive version of the original DeathAdder and also scoring high on the Rocket Ninja list, I thought that being done with this process and getting the updated version might be my final answer. The mouse was almost identical to the DeathAdder I had before with better mouse texture and lighter clicks. Unfortunately, it just felt like the old DeathAdder I had in nicer packaging. I strongly believe that in a few years, I would have ended up with the same problems as much current DeathAdder mouse. I also felt that it did not warrant the more expensive price point of $67. For a $40 mouse, it would be okay. For a $67 mouse, it felt cheap. And with mixed reviews and Razer's reputation of having products which do not last, I also ended up returning this. (3*)Nixeus Revel - Next was the fairly inexpensive Nixeus Revel. It was the first software-less gaming mouse that I tried and it had several really high points and one serious low point. I found the product to be fairly sturdy, the buttons and mouse wheel were really good. This mouse was the first one thus far to not have an LED built into the wheel assembly itself and I felt this added to the build quality of the assembly (solid block of plastic vs hollowed out wheel w/ a light). The downsides: If you left the mouse alone and let the screensaver turn on, the mouse would also "fall asleep". Clicks would not be responsive, and the scrolling would automatically switch to the lowest DPI setting. I found that if I switched DPIs, all these symptoms would be alleviated - but again, it was a really weird problem to have. Other reviewers noticed the same. Also, LED lights could not be turned off. (3*)Logitech G Pro - Lastly, I arrived at this mouse. It had good build quality with the Omron switches and even came with a braided cord. It also had the separate buttons from main mouse body and a non lit mouse wheel. LEDs were also programmable to be completely turned off. I feel that this mouse really met all my mousing requirements and should definitely be on your short list as well. (5*)
