Hellboy, I got to open the Luke FX saber yesterday finally, it's very nice. The hilt is very accurate, I'd call it as accurate as the Vader one. The movement sensor works way better than the Vader one, and hasn't gone crazy like the Vader one often does. The blue is as bright as the red on Vader's. The clash sensor is a little less sensitive, but not a big problem. To prove it's the perfect compliment to the Vader saber, where that one has only 1 clash sound, this one has like 4 or 5 different clashes! I'm doing a more detailed review on it soon here on the site, but you've got the early info.
