The sci-fi look is what sold me, but the actual warp when it spins is what keeps me picking it up. I dropped in a couple of the 1.5 x 6mm glow tubes and the whole thing lights up like a tiny spaceship at night.
The glow tubes slide in perfectly and make the warp pattern look like a tiny light show every time I spin it. I've had mine for a week and the bearing still hums as smooth as day one, which is exactly what I hoped for.
The sci-fi styling caught my eye immediately, but the real surprise is how stable it spins once you get it going—the warp effect while it's turning is genuinely hypnotic. I popped in the 1.5 x 6mm luminous tubes and the glow adds a whole other layer to the motion.
