We have a lot of power surges and outages, so I have big, office type surge protectors...three of them.
1 - sewing machines, and I unplug them, when done sewing
2 - computer and monitor
3 - hubby's med. equipment
I would like to have one on my stove and refrigerator, but can't afford to buy them right now. I had a motherboard ruined by surges in past, and the maintenance person reccommended these heavy duty s. protectors. They cost on average of 40.00 -50.00, but well worth it. They usually last at least 3 years.
I lost a really nice stove for the same reason, and hubby picked this one out, while I was too sick to go look at them. Neither of us, care for the el cheapo, stove. Spend the money, to protect your machine!
