I lost my Janome due to a lightning strike, and we lost our computer due to one, so I have surge protectors on both of them now. I turn them off when a severe storm is coming, and when I'm going to be gone for a long time. I was glad to have everything unplugged last week when the tornado came through this area. It didn't hit here, but did a number on our town, two tornados hit it with hail, wind, and a lot of damage. The first time in my life I ever went to the basement. Luckily, I didn't need to, but I wasn't going to take a chance.
