I "thought" my computer was plugged into a surge protector - alas - I was wrong! And it only took a lighting strike a few yards from my house to figure that out...So, I corrected that oversight with this excellent, quality product. Seems sturdy, a bit beefy - but - isn't that what you want in a surge protector? Very happy with my purchase - let's hope lightning doesn't strike twice! But if it does? My computer will be protected with this baby!
