Many people have clamoured for a Finalmouse Ultralight 2 shape that improved on some of the original flaws and was wireless. This BTL Grexta mouse that’s appeared on chinese e-commerce sites may be the solution for that niche. The mouse is a bit larger than the UL2 making it more suitable for larger handed users.
We have a little more information now that the mouse has been listed for sale.
122mmx 63mm x 37mm
Sensor: PixArt 3370 Wireless
You can buy the Grexta Wireless Mouse on Addice Inc
I’ll be updating the site with more details on this one as it seems to have a lot of interest behind it and will try to order one for review in the coming weeks.
