My Hands: 19x10; My Grip: Fingertip/Palm Hybrid

Hati-M:
This is a large one. But it still accepts the fingertip grip with medium hands. The hump is in the middle of the mouse (GPW clone) and allows a more forward fingertip grip with the shallower back end able to slide under the palm. I like this mouse a lot. I can rest it, full palm while browsing online or casual gaming, but switch to fingertip quickly for fps. Definitely recommend this one for larger hands. Cool tin case and awesome mouse. I was torn between this and the mm711. I may end up changing my mind down the road. Really worth giving this one a shot if you don't mind the lack of rgb and have med/large hands. Favors larger hands though.

Hati-S:
The shape is closer to the MM710/711 than it is the Mira-S. The grip is narrower than the MM710 and slightly wider than the mira-s. Issues I had with the MM711 was the hump was too pronounced at the rear of the mouse. It didn't allow for an ideal hand position for fingertip and I had to place my thumb so far back and out of reach of the side buttons that they were practically rendered useless. I would have to angle the mouse in my hand to gain access to Mouse Button 4. Now the Hati-S at first try, I didn't like it. And then an hour went by and I realized that it wasn't quite the MM711. The hump is slightly forward than the mm711. Woohoo! So this is the mouse that fits just about any grip type you throw at it for small/medium hands. Claw, Fingertip, or Palm. I play a relaxed fingertip and didn't realize the issues I Had with mouse shape until this one arrived. For fingertip, my hand position moves slightly back to give the mouse some space. For the mm711 there was a lot of compromise to make anything but claw grip work. For the Mira-S, moving my palm back changed the angle from the top of my metacarpals (bottom knuckles?) to the fingertip. I didn't like that change of angle though it was a surprisingly palmable mouse for being so small. Moving my hand positions back on the Hati-S, however, I didn't have that compromise. The angle was the same and the hump did not back into my palm as much as the mm710/711 to make fingertip implausible.

TLDR; Hati-S: The mouse for small/medium hands that can do Fingertip, Claw, and Palm. Ideal for relaxed claw. This is my current "end game".

I'm writing this review after playing 50 hours with this mouse and what a pleasant find it is! Long time user of the Logitech G Pro (80g, wireless) I was looking for something even lighter.
There is a fair amount of ultra light gaming mouse on the market but the Hati was my choice because it's shape, look and price.
This mouse is so light it takes a little bit to get used to (even coming for a 80g mouse) but after that it's a great experience all around. The buttons are super crisp, the shape is comfortable and the cable is very flexible so it's barely noticeable.
The sensor is rock solid too, it didn't skip a bit so far and the mouse skates provide a great glide on my cloth mousepad.
I'm also very happy to be able to use the mouse without any software if I want too, I set it on 800 DPI with the top button at first and have not touched it since then. There is a software I installed briefly that gives more options if one the 4 DPI presets is not your preferred setting.
There are plenty of accessories coming in the metal box, the two I like the most are the spare USB cable if I ever damage the braiding and the 2 (!!) sets of spare mouse skates. There are also additional left/right button switches, some sticky grips for the side of the mouse (it is plenty grippy without it for me) and a pouch.
A+++ experience, would definitely recommend someone on the market for an ultra light mouse to test the Hati.

Love how this mouse works and even more so how it works. Perfect fit for gaming and getting work done

I have use G-Wolves micr for years and love them. The sensor is good, build quality is nice but does feel odd with it being so thin/ lightweight.

Recommended to me from a friend, love the mouse, good weight. Great for gaming and very smooth movement
