I ordered 2 v10 neopixel sabers. I already owned 2 v5 at this time. The v10 are very nice. They actually have a real chassis, neopixel, ability to add new blade styles fonts and other stuff. Love that the old equipment still works with these. You can change the color or blade style with each font without having to reprogram the saber. That is amazing. But the 1 draw back for me is that when you turn it off, it resets all the stuff you changed and volume. So when you turn it on, it's back at 100%. I know it's not a huge deal. But that would be the only thing I would ding them on really.
