Its just a wired mechanical with a few pretty lights and a fuse basically. I'm sure they will become cheap as dirt as the newness wears off and sales slow down. I can't really see it being costly to make.
Like everything else from china, as soon as stock quits moving you see the real price.
You can get a clone nemesis mech with Kayfun 4 for under 40 I'm pretty sure it takes a lot less to make the Eone
Take something like the evic. 120-140 on release, 100 couple months later, now 55-70 bucks
