4.5 Great Tool for Doctor Who Fans idalek | 09/06/2012 | See all idalek's reviews (2) Bought this for 6 pounds 99 (can't go wrong). Its a great novelty tool and it actually works!!! I have put many a flat pack together with it. Its an all round great tool for any DIY Doctor Who fan. Ok the sound isn't the best but when will you ever want to make a stupid noise as you screw a screw in?
