Universal FM transmitter. Play music from your smart phone or tablet through car or home radio.
Was £6 now £3.
Bought from Grantham Asda, not sure if it's a national deal.
Sounds great, also plays YouTube and Sky Go etc through the car speakers. But don't watch videos while driving lol.
Comes with 9v car charger.
2 AAA batteries required if you want to play it in the house but can't see many wanting to do this.
