4 Be your own DoctorZombies8MDingo | 26/07/2011 | See all Zombies8MDingo's reviews (1)Same idea as the construct your own lightsaber product that came out not so long ago. You have components to form 3 different sonic screwdrivers, one being the current 11th Doctor's model, though the prongs don't spring out.They divide into 4 sections consisting of emmiter, control section, grip and base. The internal battery core and light slots into the grip, though it can take a little bit of force, and the control section slides on top and clicks into place. It can be a little bit awkward and stiff so younger Doctors might need a bit of help to prevent breaking it.Once built though they feel sturdy enough and look really good. Apparently you can get 80 different combinations, though it doesn't feel like it. I originally thought it just made the usual sonic sound, but it turns out multiple rapid presses of the button results in 8 different sounds.It's a great set, can imagine young fans will love having their own favourite sonic combination and I'm sure a few older fans will be getting it out of the box on more than one occasion.
