I have all my machines on surge protectors plus when I had the electrical changed over from the old fashion fuse box to breaker box I had them add a whole house surge protector. Don't know how well they protect as my old fridge blew its part that keeps the fridge cold. One thing nice about some of the surge protectors is that they will let you know if the wiring is correct. Had my electrician add more plugs down in my sewing room (basement) and as soon as I plugged in the surge protector is screamed "faulty wiring". The previous owner had wired the basement himself back in the 70's and didn't have a ground wire to it. My electrician didn't check it before adding the plugs but my surge protector called him on it. Also my APC battery backup on the backside has a added protection where it also will light up if the wiring is not correct. Had this battery backup for years and never noticed it till I replaced the battery.
Also won't call that electrician back again since he tried to pull the wool over my eyes as I asked him to check all the wiring for "up to code" and he didn't.
