Roberts Gemini RD 21 reviews: DAB and FM Radio

The Gemini 21 (RD 21) offers 150 hours battery life, which is five times more than other DAB radios on the market, so you’ll need to purchase batteries less often. Alternatively the radio can be operated via the mains and has a reduced level of power consumption. Save money and the environment with the Gemini 21. Available in sleek sliver with amber backlight or contemporary black with blue backlight, it features stereo speakers as well as separate Bass and Treble controls to enhance your listening experience.
