Review: Handy - This multi-plug extension is really handy and well made. It has enough outlets to power multiple devices at the same time without feeling crowded. The build feels sturdy, and the cord length is perfect for reaching sockets that are a bit far away. I also like that it doesn’t overheat, even when several devices are plugged in. Overall, it’s reliable, convenient, and great value for everyday use at home or for schoolwork.
Review: Versatile Design - Needed a multi socket extension for various Christmas lights. Found that standard, horizontal extension leads were no good, as the sockets were spaced too closely to one another, to be able to use smart plugs in consecutive sockets. This cube design was a great solution, not having the plugs side by side. Quality seems really great. It’s a nice size (really quite compact) and the cable length was perfect for our needs. Nice to have the addition of the USB sockets too. Nice little extension, that saved Christmas!
