Stay away from the HiHi devices, they are tantamount to fraud. Thy are not for sale and so have no specific retail price in the UK and you wind up paying £40 per unit per month forever as if you decide to end the contract you lose your 18 month 'loyalty bonus' and the price doubles. Apart from that they are unreliable, over-featured (who needs another tablet?) and easy to break and the sound quality is terrible, especially on speaker phone.
