Really? I've unfortunetly found they can't stand up to little boys. We picked up both the Anakin and Vader for them last year and within a month or so LEDs are burned out in around the same place on each blade. Typing that actually vaguely reminds me of something about the FXs I once read - is there a join in strips of LEDs at that point that might be repairable? Just odd that it's in the same place on both sabers.
And what does that say about the FX? I was thinking of picking up a Vader removeable blade, but don't like the idea of never being able to cross swords with the kiddies.
I had one, but for some reason I just grew unhappy with it. I gave it to a friend for his son. I still have the other three, and plan on buying the Obi TPM and possibly the Maul in August. I haven't had any reliability issues, but I haven't been dueling with them either.
