Review: **9.6/10 Super-Efficient and VERY Useful! Isolates Each Plug Socket + USB Ports Via Switches...** - I was actually rather pleasantly surprised by how excellent the build-quality is on this extension lead product!.. It is 10x times better than the advertisements' pictures would have you believe - they do NOT do it justice at all! (I am so glad I bought it in the end). The outer-shell is super robust, feels extremely durable AND has incredibly nice edges and 'aesthetic' to it! (Even the switches feel like premium-level quality!). It is roughly twice the size of an ordinary extension lead with 4 sockets. It's remarkably nice. I was torn-between various (black) models (towers, one's with lights, additional ports, one's with a switch per x2 ports, similar one's to this, etc...), but after days of contemplation, I am happy to report that I certainly made the right choice by selecting this one! Not only is this one more visible in low-light conditions, it is absolutely perfect for what I need it for; on my temporary set-up, in my temporary accommodation, I usually have to 'switch-out' my large, curved gaming monitor + PS5's power leads/plugs for my Wi-Fi router + Laptop charging cable up to 8x times a day (Max., but usually about 2x-4x times), which gets pretty tedious and finnicky, because I have to tilt my curved monitor to access the plug sockets, which raises the possibility for scratches & minor/superficial damage to the aforementioned monitor... not ideal, or practical! So having the ability to effectively use all of my devices, that use every socket at any time just by pressing a switch is so much more convenient - I only ever usually keep 1 or 2 on at all times, so it's great to save electric by only switching on the one's I need. I am really happy with my purchase! It is of excellent quality AND is considerably cheap/affordable, which is incredible! There are tiny 'Red' LED (lights) that indicate whether a socket/port is 'ON', which are situated directly above-centre of each port... the LED's themselves are extremely small, using absolute bare-minimum power to operate (which is a nice little touch). You can associate each socket with it's corresponding colour to indicate the exact switch (around the switches) - especially good for children I suppose (if you want them to learn which one to safely press for each device?)... Other than aesthetic reasons... On the reverse, is the standard mounting slots if you wish to mount the hub on screws that are installed on any wall/surface, for space-saving and convenient placement/orientation. Easily hang it on the rear/side of a table/desk, a wall etc... I fully-expect this to last a seriously LONG time, almost indefinitely, due to the insanely robust nature and premium-quality & care that went into the design/production of this magnificent product! It is literally THE 'perfect' extension lead, allowing you to effectively & efficiently have multiple devices plugged-in simultaneously, whilst also having the ability to isolate specific ports to save electricity and prevent overheating. Highly-recommend - exceptional product! Safe to use and Power-saving/minimal usage.
Review: Great design - I bought this as I needed a surge protector for my small electrical items that I value such as my phone, kindle, gaming controls, etc. I love that each socket has individual switches, they have a great sturdy click to them so that you can tell when you have turned them on or off easily. The Usbs have a switch which is also handy. You can turn each item off to prevent over charging and to save money on electricity which is very important with the cost of it at the moment. The 3 metre cable is incredibly useful as I take this with me when going away in the UK as it stretches across average rooms from awkward socket placements. Great to use and I also like the coloured switches. If you have the kind to brain that associates your phone with a set colour it might be fun to match it to one of the rainbow of switches.

### ⭐⭐⭐⭐⭐ Good extension lead
*by E***C on 8 June 2025*

Bought this extension lead for my daughter after her dressing table was assembled by didn't have a socket nearby. I was able to put it (5m cable) around the skirting board so as to not cause a tripping hazard. I like the fact you can switch on and off each individual socket as needed, with each switch having a different colour (which my daughter liked) it's supposedly surge protected, the price is good for this type of extension lead. Not sure she'll ever use the usb ports as they're just not equipped to deliver super fast charging that is the norm of today. The number of sockets is good, although it's important to remember the sockets are limited to a max of 13amps in total (not each) despite it being possible to max that out by having electrics plugged in going over. Lots of people have talked about the being issues with sparks etc, thankfully so far we've not had that. At the end of the day it's a 13amp socket used for multiple devices, this doesn't change the capacity of the socket, just distributes this across other devices.
