Mine (10R-1U-15T-I) arrived today. I have not yet opened the box.
I have had a Monster home theater surge unit for several years. Looks impressive with lights and meter, but is somewhat cheap inside. A couple years ago we had a strong weather event here, and power was going up and down a lot. I finally fired up my standby generator. which is surely not very clean and only makes 110-115 VAC when loaded. That day my Monster "protected" my system (which was off anyway) by blowing out a MOV. The MOV caught fire. I followed the smell and unplugged the unit in time to save it, aside from some internal scorching. I had previously opened it to replace the outlets with hospital-grade, so there was no warranty coverage. I replaced the MOV for about $0.50 and am back in business, but I have never since been comfortable with MOV protection. Depending on the sophistication of the surge device, a blown MOV might not prevent the supply of power to clients, but it negates any protection, so you might be operating without protection and not even know it.
Reading about series-type surge protection, which I did not previously know about, and the hazards of MOVs convinced me to buy the Zerosurge, and the 20% off made it even better. I look forward to putting it in.
Moral of the story: Don't count on MOV protection and do not EVER use a cheap surge protector in a plastic case - MOVs really do burn!
