Super Handy
We did have a 4 plug adapter and most of the plugs were taken up with USB converting plugs so this is a super handy extension lead and means we actually have plug sockets spare now. The plug sockets all work and its really nice to have a slightly smaller adapter to save space.

Easy to use!
This device saves the hassle of having many USB chargers, but also gives you 3 socket extension in a space saving design. Having just load tested, you can pull 2.1A with easy from the socket without a voltage drop, so thats a pass and also this is earthed so all good there. I'm currently using this at work on my desk and as per regulations, this had to be PAT tested and passed without any issues. Great all round extension and charger and good value at time of purchase. Well made although does feel a little light compared so some extensions, also the shutters do work correctly on all the sockets and the plug is a standard fused plug of the correct size!

Very compact extension with useful USB sockets
I chose this extension because I needed one with a long cable, 5 metres, rather than much shorter ones offered by other sellers. It appears to be quite well made, is very compact, and seems to work OK. All the outlets are controlled by a single on/off switch including the 4 USB outlets. I would have preferred individually switched sockets but this would have added to the size. The four USB outlets have a total power output limited to 2.1A which may restrict their usefullness. Also, I quite like illuminated USB sockets which this extension does not have, but that's a fairly small omission. If the claimed surge suppression works that is also a bonus. Overall I'm satisfied.

It's a plug bank.
This was exactly what I needed for three plugs and a USB C. The other USB ports will be useful too. Seems well made and I expect to have no problems with it. Its nice and heavy and has a clearly marked and easy to reach reset button for the surge protection feature. I bought this one and my mate ordered one straight after he'd had a look at it. That said, he now sees my ex so that might not be as good a testimonial as it sounded.

USBs are shared
I bought this extension for the living room as I wanted to have a central place where all phones/tablets could be charged rather than having to cart around differnt wall chargers. In that sense it has been useful so far as it has lots of usb charging ports. My only issue is that the ports share power, so one plugged in by itself will charge quite fast but if all the ports are being used then the charge is relatively quite slow. I purchased the 5 meter cable option and this may have been a tad too long as it the wire does trail somewhat, maybe the 2 meter option may be a better option in the lounge. I don't believe it will great for traveling as it is quite bulky so a powerbank would be better there, however saying that I haven't tried taking it on my travels yet. The colour is white, I'm hoping it stays white rather than going off-yellow like the old school extensions used to do. I hope this review was helpful.
