Micromatic WS-2910 Electronic Voltage & Surge Protector for Microwave Oven | Protects Against High and Low Voltage, Brownout, Spikes, Power Failure. Includes safety delay time

I ordered this after installing 2 of the same brand on my dishwasher and washing machine. A decent price to protect more expensive appliances. The device provides a delay (while showing a specific LED before power is restored after a power cut) as well as a mild chime to say power is restored to the device. Certainly worth using.

keeps sensitive electronic safe safe during surges

I’m very excited about this item. Our last microwave got ELECTRIC shocked in the currents from a storm and died so I’m hoping this one will save us. It looks like it really works. I have it set up so I can look at it and see it. I’m hoping this will save me from a new microwave purchase

good counter surge proctor but It was too late. Microwave was already put in cabinet. Picky meg

Work as expected.

Great item

Received this afternoon to use on a new microwave oven. Due to power fail/restore and brown-outs, my old microwave oven only gave the faintest audible alerts when heating was complete. All other functions were good but I’d like to have an audible alert when cooking was complete. I have, for years, a surge protector/line conditioner that constantly displays the ac voltage from the power company I use for my audio/video equipment. Watching the voltage when power restores after failing or when there’s a brown-out is an eye opener. The voltage can drop to near 100 and rise to 130. At one particular time the power company had severe problems. The voltage fluctuated from below 80v to over 150v. Many people lost fridges, air conditioners, tv’s, etc. After reading that this unit actually doesn’t send power to the microwave for about 30 seconds after commercial power restores, I had to buy it. I have simulated a power failure to see if it really works. It did! About 30 seconds after power restored to the outlet the microwave powered on.Considering how this protector operates, I think it’s a good value.Note: When commercial power restores the voltage usually takes several seconds to settle down. This can be the hardest on equipment.Also note, regarding other comments regarding the instructions, the single page with the device is equal in both English and Spanish. They both say the same thing. This device is about the simplest thing to use. Per the label on the device itself, plug the equipment into it (the microwave) THEN plug this protector into the ac outlet. The led’s on the front tell you the status. You should see a yellow light indicating Delay Period. After about 30 seconds the unit will click and the green Normal Voltage led will light. Thats when the microwave will power up.

I just lost a microwave after a hard power surge and I knew it would happen again. I got a one pack of these to try it and it's working great. No more problems even though all the other appliances flicker. I got a 4 pack so I can protect my oven, fridge and other expensive items.

Fue el primero y cómo funcionó muy bien, compramos el paquete de dos. Si lo recomendamos.

In Nova Scotia we have innumerable power outages, and the time delay on line re-energizing helps eliminate the unavoidable spikes reaching the appliance.

El protector electrónico cumplio con mis expectativas, buen producto, buen precio, gracias vendedor y Amazon.

Works well as surge protector on fridge

Llevo apenas un par de semanas con el y he tenido ya una variación de voltaje en la que demuestra que funciona muy bien, Para todos aquellos que dicen que no cambia el led de color y no pueden usarlo deben estar consciente que deben dejarlo conectado por máximo 3 minutos hasta que los capacitores estén llenos o de caso contrario revisar bien el voltaje y amperaje de su hogar
