Good quality
Robust build. Bought because power in my area can be dodgy and had lost a piece of kit through a surge. So far, does what it says and the usb ports charge fast. Definitely value for money.

Small and neat
This product is in a small form factor which had made it perfect for my use. I have used this item to protect my pc from power surges. I have avoided using an extention lead as I wanted clean power for my pc. A normal UK socket does not have surge protection so this small product offers a great neat and tidy solution. I have not yet used the usb ports but is a great added bonus to have them included. The product is a seems to be of good quality

Excellent. Bought the same item years ago and it finally died.
I bought 2 of these some years ago and one has been in constant use both here and abroad. My daughter "borrowed" one for her holiday...and it now lives with her! My sockets have inbuilt twin USB sockets but I have a short extension lead to where I sit and use this adapter from there. The 2 internal lights stopped glowing a long time ago, but the unit has continued to workway longer. It finally stopped working this week and I was so pleased to find that they are still manufactured.

Works Brilliantly
I’m a gigging musician who uses a rather expensive Bose sound system and sometimes during play at some venues, especially pubs and clubs, the electrics surge and causes spikes which pass through my gear, which can be quite a worry when using a two-grand rig. I was told the problem was likely a power surge caused by multiple appliances using the same ring and was advised to get one of these and it has been a total game changer. It has cured all those annoying (and worrying) spikes and is now permanently attached to my main power lead. Such a small price to pay for that peace of mind. The USB ports are a useful feature.

I plugged a mini-fridge into the same power extender as my PC and LG C2 monitor. Every time the fridge compressor starts/stops, it interferes with my LG C2. I put this on the power extender and plugged the fridge into that, and the problem has vanished!
