I was given the opportunity to review this mouse, so as a disclaimer, I want to mention that I received this product for free. However, I was given full control over my review and impressions.

First impressions are solid. I'd heard of Redragon before and knew they were quite popular, mainly in the budget keyboard space. I've tried one of their keyboards before and was quite pleased with it, but I didn't have any experience with their mice until now.

I played some Cyberpunk, Sniper Ghost Warrior Contracts 2, and Sulfur with it and had no issues. The coating feels good and doesn't feel slippery, there was no sensor skipping, no connectivity problems, the main and side button clicks feel good, and the scroll wheel works well, though the steps could be a bit more tactile.   
  
One small thing that isn't necessary, but is a nice touch, is that the front side button has a different texture than the rear one. I quite like this idea.

The sensor is an optical Pixart 3395, with a maximum of 26,000 DPI and support for a 4K polling rate. As mentioned above, I didn't experience any issues with the sensor, but I also didn't really notice much of a difference between the standard 1K and the more performance-oriented 4K polling rates. That could also be because the games I play don't really focus on competitive play, so someone who plays more competitive titles might notice a bigger difference.

As for its shape, for my hands and grip style, it's not the most comfortable. I've got pretty beefy 19 × 10 cm hands and use a relaxed claw grip, so the narrow sides left me with a slightly cramped feeling around my thumb and pinky. I compared it directly to my VXE R1 Pro Max, which is my daily driver, and found that its shape was more comfortable overall.

Overall, based on my impressions, it's a good-performing product at a decent price. However, there are two things I would've liked to see included in the box at this price point: some grip tape, which I know isn't for everyone, but I personally enjoy using it, and an extra set of PTFE skates instead of the regular ones. Compared to my VXE R1 Pro Max, this mouse definitely has a bit more drag.
