Sold out at Gearbest
First version because I’m not a fan of eswitches
found it on Amazon for just over $50 (seven left when I looked)
also looks like GoingGear.com has some, too ($50)
… so how hard did you look? Those were both on the first page of my google search…
I have my regular go-to sites, too, so no offense intended.
good luck with your hunt
Why not buy the Astrolux S41? It’s going for $32 on banggood.
