It does exactly what it says on the tin - that is the verdict of one reviewer trying out BT's iPlate device.
According to Barry Collins of PC Pro, the £10 device improved his connection by 63 per cent after a couple of days, rocketing from an average 1.9Mb to an impressive 3.1Mb.
Mr Collins pointed out that the device was Quick-and-easy to install, attached to the master phone socket at an address.
He commented: "It can take up to three days for BT's automated equipment to adjust your BRAS (maximum speed) profile once your synch speed improves, but within 36 hours my BRAS had been adjusted to 3.6Mb and I was surfing at vastly improved speeds."
The BT iPlate works by reducing electrical interference from other devices around the home such as televisions and set-top boxes.
