hmm well, in my opinion, the overall is good...
but, the 'fat' neck really bothers me and it really took away the look...
and the sound... the power-up sound, I don't think Luke's RoTJ saber sounded like that in the movie...
it sounded more like a 'high-pitched' power-up sound... but the LS MR sounded like any other 'regular' or common saber.
but other than those two, it's a top notch... the weight of the hilt + blade, it's pretty light, just like what a real saber on the movie should be... *coz, you know, you can't really weigh the blade, since it's a light ^^
