I have only just recently come across these fx lightsabers by master replicas. I love the whole ideal and notion of star wars, but wouldnt call myself a hardcore fan. However, this lightsaber is beginning to convert me more and more to the star wars empire. The detail on the hilt is absoultely phenomenol, and its very heavy, so not really a toy, although im sure no one can resist having a proper duel with one of these beauties. The blade itself is very good also, and the sound effects are awesome. I also own a darth vader blade, but this one has much better sound effects in my opinion. The only problem I can think of is the packaging or lack of it comes. All you get is the lightsaber box itself and a bit of plastic wrapped around it. I know play.com offers free delivery, but nevertheless it is much easier for the sabers to be damaged this way. Luckily enough, my ligthsaber was fine. So, in conclusion, I would highly recommend one of these, simply because they are a great collector's item. Be quick, because the darth vader one is now out of stock on this website.
p.s. if reviews like this dont covince you, go on to youtube and see for yourself these amazing lightsabers in action.
