I got a Mace Windu FX lightsaber yesturday. There seems to be a problem with the blade though. It doesn't light up consistantly. The best way I can describe it is it looks like a tye-dye shirt the color is blotchy all the way along the blade. The color is not consistant at all. It varies from purple to pink to lavender. I took it back and tried the other 5 they had some were worse I took the best one. Does anyone else have this problem or is this the way their supposed to be?
