Micromatic WS-2910 Electronic Voltage & Surge Protector for Microwave Oven

Product works great. The cost was reasonable and should protect my new appliances

I've had this for years and happy to report no I no longer have issues. I did have microwave fuse issues prior to getting this, so I bought this item and a new (same model) microwave and never had a fuse issue again.

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 really like this product, it give me peace of mind the appliance is protected. We have power outages in my area.

We assume it is doing what it is supposed to do. We don’t see it unless we go looking. It arrived on time and installed as expected. What else can one say.

It's up there; silently doing its job. We bought it because with every power blip, the microwave had to be unplugged then plugged back in to continue working. So far, I haven't had to cycle it.

Llego en tiempo. Funciona a la perfección. Protección para los equipos electrodomésticos

The protector is working fine. Living in the lighting capital - The Villages, FL, you need 3 levels of protection. This is my second level of protection for the microwave.It gives me peace of mind knowing the microwave will not get zapped.
