ZYGEN (VAXEE) - E1 Wireless (4K)

I have the same size hands and had almost the same problem with the same mice - aggressive claw grip so no pinky dragging, but I had to curl too much for the HyperSpeed. Landed on a Vaxee E1 and it fits me perfectly.  It and the Zowie EC2-DW its shape is based on are worth checking out. The E1 sometimes does feel a bit short in my hand, but the EC2 is supposed to be a bit longer so it might work better for you since your grip seems and sounds a bit less aggressive than mine. Consider nabbing them secondhand if the price is prohibitive (they pretty much don't go on sale ever). edit: Also important to note those Deathadder shapes you tried are based off the EC1/2, so it'll be a familiar shape to you.

have the DAV3HS and had the same issue with it being slightly too small, very similar hand size as well (less wide by .5cm). Vaxee E1 is a really good fit for me. essentially the same shape yet sized up by a slight amount, most noticeably in the back where my hand sits quite a bit higher. for a significantly more supportive mouse, pulsar zywoo might be a good fit.

The best ones in my opinion is the Dav3, Vaxee E1, Gpro Dex or wait for the EC2-DW.

Also, look into the vaxee ergo they released recently. That thing fucking rules

It's been my main for a while now. Kinda the closest thing I've seen to a true symmetrical ergo hybrid and it's vaxee so it's built like a tank.

I've had nearly 0 problems with any of my mice. Vaxee and EGG seem especially solid though. Only mouse I have had issues on if i remember correctly is the original g pro wireless. Started double clicking

Personally if I was concerned about durability id get a vaxee mouse. They are built like tanks. I've never had an issue with them. Build quality is crazy good.

For me, it's EGG or Vaxee. Neither are following the "mega-ultra-super lightweight" philosophy, they care more about making incredible products. I've had my NP-01S v2 for around 6 months and I only regret not buying a Vaxee years earlier.

Pulsar V3 es or Vaxee E1 2 of the FPS goats

Vaxee Best clicks on a mouse

I have all or most of the mice mentioned in your post, and similarly have had issues finding a mouse that had a right side that felt normal. The XM2w caused my hand to cramp (even tho I played awesome with it lol) The E1 is the best overall mouse I've ever used imho. The shape is second to none in my opinion. I have the ec2-dw, the pulsar super light size 1 & 2ES) and many other ergos that aren't nearly as comfy. The cons to the E1 are - the buttons have a specific bounce/spring to them, so there is a tiny bit of rattle if you slam your mouse often - the scroll wheel is fine - the side buttons have a bit of a corner to them, (I just sand it down) I'm currently switching between the E1, the Viper V3, the Zowie S2-dw Oh, and the Sora is an awesome mouse with a great shape. It's god a cool internal structure that was fun to mod and get the weight super low. I missed having the curved finger grooves (so I added my own) but overall it's an awesome mouse that I mained for months before I got into ergos. The pulsar super light is awesome, but had specific curves (along the right side and front) where I never felt 100% comfy. I have the v3ES and the v3 size 1, and both were a bit off for me. And I also didn't love the raesha optical switches.... Best scroll wheels tho! The XM2w is certainly the best built mouse of these three. If there was a version that didn't have such an aggressive inward curve along the right side I would likely be maining this mouse. That and I wish it had finger grooves... It's so solid tho... My personal rankings: 1. E1 2. Sora 3. Xlite (does the v4 still use Raesha optical switches??) 4. XM2w (but if you like the shape, its potentially #1)

I'm loving the Vaxee E1

Vaxee E1

Because even if your palm grip is “forced” to the right side, the ec2 shape should be the best option available, and since the vaxee e1 is the a better ec2, this is why I think it would fit

The g502 is very similar in shape to the G7 but has more buttons, uses Logitech software (not sure if there's a web based software or if you still need to download Logitech ghub which might be an issue for using Linux, not too sure).  The vaxee mice have the highest quality reputation from all these choices and would probably suit your needs well but I'm not sure if they have Bluetooth connectivity (same goes for the Logitech mice in that regard).  The Vaxee NP-01, E1 or XE are probably the best of the options in my opinion from those you've listed as they have great tech, and great build quality. I'd usually say that some sort of ergonomic mouse would suit him since he's using it for long periods for productivity and not too much for FPS gaming but if he really liked the model o shape then the Vaxee XE should be close enough shape wise to make him happy.
