Im really not impressed with these at all. To me, they are really unattractive and look cheap. And they're HUGE! The crystal concept is the only interesting thing I see but its not enough to redeem these awful monstrosities.
I like the CC swapping feature, but jbkuma did it better, though. I also do like that no-blade detection sparking sound. Could be a fun thing to implement into Neopixel sabers. and not too hard to code into arduino, either.
But yes, they do look like cheap Hasbro knockoffs. Which is impressive, given they're made of metal and cost upwards of two hundred bucks.
...I wonder how long it'll be before:
a) someone on the saber forums rips one apart, so we can have a good laugh at what's inside,
b) the forums start getting posts asking for help adding Crystal Focuses to their Galaxy's Edge toys.
