Surge protectors are tricky. In the UK, our power supply is pretty clean |
| 15 |
so they're (almost) a waste of time. They should have a status on them, |
| 16 |
usually they're good for one shock and that's it. The big danger in many |
| 17 |
places is a lightning hit on overhead power lines. And if it's a storm |
| 18 |
you can have several hits in quick succession which will overwhelm the |
| 19 |
protector ... |

Again, you need a decent unit. And they're mostly a lot cheaper than a |
| 28 |
computer, so if they take the hit rather than your computer you're quids |
| 29 |
in whatever. But even if they're a not-very-good unit, if your local |
| 30 |
power is crappy they should clean it up and protect your computer to |
| 31 |
some extent. |

The problem is, I'm in an area where the protection these things provide |
| 38 |
is pretty redundant - I'd probably be fine without them. If you need |
| 39 |
them, as I said the danger is they're overwhelmed right at the start and |
| 40 |
then your kit gets damaged along with the surge protector and UPS ... |
