Fits like a glove in my hand (20x10cm). As per title the LAMZU Thorn is perfect for claw/relax claw grip and can work palm too. The subtle hump in the back of the mouse creates a lot of support for the base of my palm and provides a good locked in grip when playing. Ergo shape feels nice, especially around the area where my right ring finger and pinky go. No pain or aches or “break in” time for that area.Coating is good and quite grippy even without grip tape. I also have sweaty hands and the mouse handles it nicely lol; however I’ve noticed finger/hand prints sometime stay. The 3395 sensor feels great. Currently using 1khz polling rate, 1600 dpi, and motion sync. Might upgrade to 4k later but haven’t really felt the difference in higher polling rate from my experience with other mice.Feet are nice but I have limited experience with other mouse feet so I can’t say much. Clicks are nice but a little loud. I don’t feel any pre and post travel with the clicks. Software is pretty robust for me and satisfy my needs. See pictures for more info. Battery life feels good but I charge every day/2 days so I can’t comment how long it lasts.Overall, looks like I found my endgame mouse ?. Other mice I’ve tried:Deathadder v3 wired: can’t get a comfortable claw grip with this mouseSora v2: ring finger pain galorePHYLINA S450: shape was okay but I was plagued with QC issuesPwnage custom Ambi: original claw grip main but developed double clicking issues.ZA-12C: decent for claw but wire and weight swayed me away.
