Having tried Struth's clawmates and a project called Hyperwings, this is hands down the best mouse shape adjuster I've used. I've got aggressively wide hands that are mostly palm (19 x 11 cm across the palm with a 7.5cm middle finger) and mice don't feel right. I've got a buddy who was kind enough to share over 30 mice with me, and None of them fit or feel right, almost exclusively because there has never been one wide enoigh to accomodate my pinky. From the deathadder v3, lamzu thorn, g pro wireless, glorious model d and o, htx, and beast x, they all feel uncomfortable and my hand will cramp and ache because I'll have to scrunch my hand and hold the mice at uncomfortable angles. Only the mm720 has worked, but that mouse sucks.
The passive 1 and neutral have been able to fix this mouse grip and width problem in the way I've been searching for that the hyperwings and clawmates were not able to come close to.
The passive 1 gives me a much needed place to rest my pinky while also having a big enough surface area that I'm able to adjust where I place my other fingers. It's let me use super lightweight mice with comfort I've wished for since I was first enamored by their lightness.
Aimlabs and gameplay has never felt better. My name on aimlabs is NickKnacker for anyone who wants to look me up, and the most recent voltaic and aimlabs ranked scores has been with the beast x or thorn and passive 1 or neutral sos grip.
