Spotted these instore today. Long been discontinued and only a few places still do these @ around £35 each.
Based on R2s look from the original trilogy, R2-D2s head spins, a light flashes and the R2D2 sound is produced whenever there is an incoming call. Demo mode. Redial, tone/pulse.
The helmet unit also features three sound effect buttons, producing realistic recreations of the saber swing, the Imperial March and of course, Darth's famous heavy breathing.
The Darth Vader Phone also features a standard ringer mode, ideal in case you have elderly relatives with weak hearts/bladders visiting. Other features include electronic push buttons with tone dialling and a last number redial function. This is a phone you just have to have if you're a Star Wars superfan.
Measures 30cm high. Uses 3 x C batteries
