Good power cut device... but check your voltage.
30 May 2019
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 you need a power outlet with the giant pins to plus this into... like the giant AC or refrigerator outlets... it will NOT fit into normal outlets.
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).
