Fydun 30KW Home Power, Saving Box Energy Saver Stabilizes Electricity Saving Box Electricity Powersave Voltage 90‑250V with Capacitor UK Plug

I have been using this device now for 2 weeks.Would I buy another. Yes I have suggested to family the savings.I have fridge, tumble dryer, fridge/freezer and dishwasher on same circuit. I am saving just over a pound a week. I paid £10 and should save over £52 a year. Doesn't sound a lot, but anying helpsI decided to purchase one as I know from my working days, fridge and freezer used to show spiking and crashed telephone systems

Just an led in a box, noting more, nothing less. Could also be considered a fire risk, it is just two 12v wires soldered directly to the back of the live and neutral pin of a uk plug. There is absolutely no safety, no protection, no fuse, no earth and should there be any kind of short circuit it would just melt. So unfortunately this item 100% won't save you a single penny.I didn't actually purchase it my 81 year old grandfather did. I ask him why on earth and then I did try to explain I didn't think it would do much at all, and probably didnt have much inside. So we decided to open and have a look. The deal was if it did have something substantial inside I would replace the item myself. If on the other hand it didn't, I would take him out for lunch instead. Well it cost me more to take him out for meal than this plug would have cost to replace. However you honestly can not put a price to know he doesn't have some doggy fake fire hazard device plugged into his home. Please save yourself money and potentially your home or even your life.

Seems to work as advertised

Dangerous junk do not buy !!!This is simply a couple of LEDs and resistors wired directly to the mains supply pins.It won't save you money, it may cost you a lot more (your house or your life).Amazon should not sell this cr*p.
