I received this note from a priest friend:
I got an APC BACK UPS ES 550 the other year upon your recommendation on WDTPRS.
Last night, while sending you an email[!], lightning struck directly three times in a row.
And the BACK UPS is still working.
Thanks for the advice. It would otherwise have been a personal TEOTWAWKI event for me.
Today a storm raced through. There was lightning. Several of my UPS’s registered small surges.
If you don’t have one of these for your computer stuff, your big expensive TV, etc., you’ll be sorry.
Avoid Ultra. Terrible customer service and unreliable units. Use APC. They do it right. I have some small ones for less important items or things that consume less power. For the important stuff, I have massive UPSs. When one of these APC units “died” in the defense of my stuff, APC was great and sent a replacement unit. Ultra… not so much.
Weigh the costs of replacement and time and loss of data against a the buffer. They are not absolute, but they have saved my stuff several times.
I really do mean to scare you when I say that it is not a matter of IF you are going to have a big power surge or a hard drive failure, it really is a matter of WHEN. If you don’t prepare for the day, you’re nuts. Spend a little now or, later on, cry cry cry.
