update : since we have only 5-6 recon users on this forum i confirmed the polling rate myself issue by having a little chat with a proffesional hardware reviewer.
Average polling rate fluctuates between 427-429hz constantly but that doesn't seem to affect cursor quality or anything, feels much more precise than the zowie 3090 mice if you ask me, especially on rough black colored surfaces like my hien soft, cable is kinda stiff but still better than spawn and IMO 1.1, i wanted it to be like logitech g400/ zowie EC 1st gen( AM/evos have sligthly stiffer cables ) but i can live with that
sensor keeps up with low sensitivities just fine and the LOD is adjusted to just over 1CD ( 2/5 setting )
Mouse is indeed heavier than ec2 ( ~ 15 grams more ) but due to its unique symmetrical shape and smaller mouse feet i can be much more "agile" in-game, i can also lift and reposition it when i have to with no effort.
Keep in mind that i have small hands, my fingers are kinda short and chubby so spawn was pretty a good fit for me, minus the extra stiff cable, very high LOD compared to zowie mice and some pinky pain during those long fast swipes over the mousepad
