This surge protector claim to fame is that it has 330V Clamping, 2500 Joules, and is name brand. I could not find if it is UL Certified. The 330V clamping is not always found on surge protectors in this price range. This is cheaper than Amazon, $28.94, cheaper than Newegg, 24.99 and cheaper than Walmart, $26.99. I ordered 3 of these so I got the free shipping. I did not use the 15% coupon, found out about it after I ordered. Did use a 10% off coupon that did not require email sign up.
