Smart Plug High Low Voltage Protector @ 6Amp Rating with Surge Protection Upto 4000 Volts_SPGBW (Black)

I have purchased 3 months back and iam giving review .. it's nice product small in size and big in work .. value for money and working fine .

Works well. Cutting off power when high or low voltage coming

Working for a week now without fail. Operating as promised. Haven't really checked in extreme voltage fluctuations yet. Price is reasonable. This is quite convenient compared to Voltage stabilizers because of its compact form. Fits directly to socket saving wiring issues and space. Convenient to carry along too as is relatively portable and not heavy.Will update as fluctuations in power supply is expected in a month.Con:* does not fit very well in certain sockets. Pins bit thinner than standard.* too big for some prefabricated modular switchboards. Input Power plug sits midway to the top extending the unit on both side of the socket. This causes user interference with switch over the socket.Overall a good buy. Value for money if it last an year

And it protects our appliances perfectly and worth buying

This voltage cut-off outlet works pretty well... cuts off at 270 Volts for sure (couldn't test the 165 Volts low cut-off). Just check what voltage you are regularly getting where you plan to use this. In guesthouses in Goa, some days this device constantly shuts off... then sometimes turns back on a few minutes later, only to shut off again (due to constant high/low voltage)... so as long as you don't have this type of situation, this will help protect your devices from over/under surges. Note that this will fit into normal outlets (the 16 Amp version of this product requires a giant AC or refrigerator outlet).As for the max voltage it can handle, well, can't really test this without risking an explosion :)If low/high cut-off is what you need, I think you will be happy with this product. Note that this is NOT a surge supressor or protector that helps dissipate surges. It is only a cut-off... so if you get a big surge, it will not dissipate the surge... it will pass the surge to your connected devices until the cut-off triggers (usually only a fraction of a second).Anyway, hope that helps... please click "Helpful" below. Thanks!

Very useful product for costly home electrical appliances just plug and be worryless.

stopped functioning within a week of use.

I bought it for my Sony 75 inch TV. The power socket is connected on inverter line. As a precaution i have used this smart plug. whenever there is power cut this smart plug is tripping and it takes more than two minutes for my TV to restart. with out the smart plug TV used to continue with a small flicker. I was worried that the flicker could cause trouble in longer run and thought of this smart plug. But this one is tripping frequently that could also lead to some trouble. After using it for few weeks I have removed the smart plug. I would have chosen this option during the return window.It needs to be designed to arrest the spike with out tripping.
