Hello, I needed more outlets so this unit has to go. It is arguably the best surge protection available. http://www.pricewheeler.com/bestprot.htm NON MOV (Metal Oxide Varistor) based so protection will never deteriorate. MOVs are sacrificial and WILL over time become useless. This is a near perfect unit, 20 amp plug so you'll need 20 amp wall sockets but it accepts either 15 or 20 amp plugs into it. I used it upstream from a Tripplite isobar to protect and filter my whole system. Also a great RF EMI filter http://www.pricewheeler.com/conditn.htm - I did a ton of research before I bought this and you can't beat it's protection! Especially for the money. I've moved up to another with more outlets. Shipping is $10 flat to US/Canada. Paypal is preferred with no additional fees. Asking $150, paid $225 less than a year ago - this piece is mint! Email me for pictures or more info!
