Great mouse

I got this for work so I use it 8-10hrs a day. Im using the wireless dongle it came with for the best sampling rates and it's very smooth. The battery seems to last quite a few days and sleep mode seems to not drain the battery since it I can leave it for a week and its still charged up. I do wish there was a battery indicator for MacOS but it at least turns read when the battery is low.

It feels good in the hand and is weighted perfectly for me, especially with the weight at the bottom.

Ok mouse, long battery life

Looks pretty good, and feels really good in the hand.
I really like the matte body and the fact that the finger rests for the thumb/pinkie are textured plastic instead of stickers or painted-on since they won't degrade over time but the inward slope on the right side is a little uncomfortable on my pinkie.

The rgb behaves well and can be turned off without any software which is very important for me since I'm on Linux.

The battery life seems pretty good.
The usb cable would be very good even if the mouse was wired but the long connector and the fact that the port on the mouse is not recessed enough means that it's a bit uncomfortable using it while it's plugged in.

My only real issue is possibly with the sensor which doesn't seem to work on some surfaces that none of my numerous previous mice had any trouble with, resulting in choppy/laggy cursor movement - I verified this by using a piece of cardboard under the mouse which seems to work very well.

Great mouse

Nice mouse! Feeling 100% Thanks!

Pleasantly surprised

As others mentioned, at first I was disappointed because it didn't slide well compared to my previous logitech mouse.
Then I found out, that there was a thin protective film that I had to remove.
I love the fact that it is a little bigger than my logitech mouse.
And I love the sharp price.
I love the USB-C and all the accessories that are included.

But maybe the accuracy is just a little lower than the Logitech mouse I had previously.
The buttons aren't configurable yet. But I hope that will be fixed once the Mac driver will be out. (expected in June).

It would be nice if it the mouse buttons would just configurable using the VIA webpage that my keychron K3 pro wireless keyboard has.
But I guess that's an unrealistic expectation. Curious though, and really looking forward to whatever solution is coming up.

PS: I am a software developer with budget for cool gadgets and extremely high expectations. The K3 keyboard really checked all the checkboxes. When I found out that they shipped a low budget mouse, I just ordered it along with it, not expecting too much of it. But I actually like the mouse as well.

Great Mouse

Really great Mouse!

For people complaining about the rubbery slides. There is a blue protective film on them that you have to remove.
