Ok my first Lightsaber was Darth Vaders (A lovely saber, with real metal hilt, nice and heavy) so after getting that one, I decided to order Lukes and Yoda's at the same time :D
(I'll give a review for Yoda's on that page...I wasn't happy how that one was packaged :()
but anyway, on to this saber, firstly this was the only one that came in the original Master Replicas warehouse outer box (which I was extremely happy about :) so I knew that the whole thing was in mint condition.
so now on to the lightsaber itself, firstly you'll notice how light it is, compared to the Vader blade (real metal) the Vader blade in Hilt heavy so is slightly more balanced, the Luke saber is blade heavy, so is not well balanced, but that's not too much of a problem as it makes it easier to spin. now on to that creaking that you have no doubt heard about, it's actually not that bad, I have to say I haven't really noticed it that much, so i don't see it as a problem.
The sound effects are definitely the best of the 3 sabers I have, I say this, as this saber is the most responsive of the 3, the Vader only has one clash effect, and doesn't repeat it until it has finished playing it, whereas the Luke one will override a clash effect with another clash effect if it is hit again and again, and the least said about the Yoda saber the better...you nearly have to smash it against something to make it clash...which is not good at all.
a very good saber, probably one of the better ones if you fancy having a duel as the clash will actually work properly.
