For me, the star of the brand itself is the Asteria Board. The variety, the coloring, the duration of, say, the retraction or the flow of the waves on a fire blade, everything is customizable and easy to do so.
The community built a very comprehensible and rather complete document to learn how to tweak the blade styles to our liking, including sound mixing.
The saber itself is almost perfect. Proportions are on point, sound is great, not muffled at all, the LEDs are strong... the only two things they could improve on for, say, a V3 of the product is to implement a real SPINNING crystal and have the sideblades be at a fixed position from factory; make it a choice, like the game, on the angle of the sideblades and have it be fixed so you can also improve their strength.
Other than that, 9/10 saber. I love this thing
