The quality checking of the Microtek is so bad that I returned the product twice.....better to avoid this product

Not very good product

The unit basically cuts off 37V from the overvoltage, which is rather crude. Here are some examples i measured at home (input vs output):220V -> 220V, 230V -> 230V, 240V -> 240V (Unit is on, but not active -bypass mode-)245V -> 208V, 250V -> 213V, 260V -> 223V (Unit is actively regulating)I had expected that the output is always 220V with just a small variation (maybe +/-5V). But its not.Good thing is however that the switching from bypass to OV protection happens extremely quickly, so there is no outage or voltage drop.All in all it's a solid product, and it helped me a lot in protecting my valuable electronic items and edison light bulbs.
