Ok so... we have seen a few of these pop up on here recently.
Most of them have been around this price or slightly cheaper, but this is one of the 'safer' cheap options for people worried about the items safety.
This one is ASTA Approved, Manufactured to BS 1363-2 and EN 60950-1.
So this one shouldn't* burn down your house whilst you sleep.
Worth the extra couple of pound for peace of mind if your worried about the cheaper eBay/Ebuyer ones.
The USB sockets also seem to be better placed than some others.
White moulded outboard rocker socket with 2 x 2.1A USB ports. Ideal for charging iPads, iPhones, tablets, mobiles, cameras and more. Features angled, in-line terminals and includes backed out captive screws for easy installation.
