content: I bought a 25$ redragon with 18000 DPI. turns out the DPI is more like 4000 at best upon testing and was upscaled to 18000. Whereas the logitech mouse performed as required. Do you want your mouse to not detect movement for a few micro movements and then suddenly jump pixels? no. If you move your arm around, you can have a potato mouse. But some of us like not moving our arm and thus we need a sensor that can properly detect the compressed resolution space. So in my experience, definitly not even close to overpriced.
