4.5 Just the same as any of the others TardisMonkey | 15/04/2010 | See all TardisMonkey's reviews (2) Bought the Sonic Screwdriver today due to that I needed a closer replica to the one that David Tennant has on screen. Thats what I got. Its the same material as any of the other Sonic Screwdrivers and even makes the same noise and has the same functions. Only problem was that the cap that covers the screw does not fit properly and maybe easy to loose.. So watch out!However its a good cheap replica for any who fan.
