Good single extension for the price.
I ordered one of these to extend my 7 way extension - as long as both are rated for 13a and current isn’t exceeded , it’s usually pretty safe. The housing is made of plastic but seems decent quality and it does the job perfectly , the cable is nice and thick but it is shorter than 3m (not by much maybe 20-30cm) so if exact size is a priority , get a longer one just to be safe.Overall , it does its intended job and I think it’s worth the money.

Single socket, flexible cable, child-safe, surge-resistant. Solid value for simple power.
This extension lead is built for simple, single-appliance power access—ideal for plugging in a laptop, printer, fan, or site kettle when the wall socket’s out of reach. The cable is flexible and lightweight, making it easy to route behind desks or across floors without bulk.The child safety shutter adds peace of mind in shared spaces, and the anti-thunder protection helps shield devices from minor surges. It’s fully fused, and the copper wiring (H05VV-F 3G 1.25mm²) handles up to 3120W—enough for most household and light-duty site gear.✅ ProsSimple and reliable—no frills, just solid power deliveryFlexible cable—easy to route and storeChild safety shutter—blocks accidental contactMultiple lengths available—2m to 10mAnti-thunder protection—adds surge resistanceBudget-friendly—often under £10⚠️ ConsSingle socket only—no multi-device supportIndoor use only—not IP-rated for outdoor exposureNo power switch—always live when plugged inWhite cable can stain—shows wear in dirty environmentsNo mounting holes—not ideal for wall fixing🧍♂️ Personal VerdictUsed this in a garage and site cabin—plugged in a heater and kettle with no issues. The cable’s flexible, the plug fits snug, and it’s ideal for single-use setups. For under a tenner, it’s a proper bit of kit when you just need one reliable socket with reach.

The Loneliest Socket in the World
I've never seen such a beautifully solitary outlet. This little guy stands proudly on my wall, serving its one, singular purpose with unwavering dedication. While all the other multi-gang power strips are having a party, this one-way gang is a true introvert, perfectly happy to power just one thing at a time. It’s a very high-quality product that does exactly what it says on the tin. My only minor gripe? It’s a bit of a socket-able offence that it doesn't come with a tiny party hat for its lonely plug.A perfect purchase for those who like to live life one plug at a time.

Reliable and Does the Job Well.
I bought this single socket extension lead to give a bit of extra reach for powering a device in a corner of the room, and it’s been perfect. The 3-metre cable length is generous and very useful, and the build quality feels solid. No issues with performance — it delivers consistent power and fits securely into UK sockets.Simple, reliable, and exactly what I needed. Great value for the price!
