You can check Lamzu Thorn or other mouses from them, although beware you can't connect via bluetooth, only 2.4G or wired for this model. Personally bought it, still waiting to arrive.

I heard also good things about Logitech G305, it's cheaper than Lamzu Thorn, but again only 2.4G, and it has an egg form if you like it. Also I was tempted to buy MCHOSE G3, which has same egg form, wireless with bluetooth/2.4g and wired, but feared the quality control. I would've bought the G305, if it wasn't for double click issues I had with G102, for both clicks, although to be fair it's older than 2 years..

Also as @nout pointed out, check Logitech MX Master 3S/4. If you can pay ~115-130$ for a mouse (where I live it reaches $186), and version 4 even more so.
