I own two of these, and will probably add 2 more pretty soon as I am expanding my network cabinet and home office. The long cord is fantastic, the tel ports are pretty obsolete… but If the fuse blows and cannot reset, it stops working. 10/10, properly designed equipment protection. If your gear fries because it did not trip, there is insurance. Nothing tells me you believe in your product like putting money behind the promise of protection. Honestly I think at $18 this thing is truly the best you can buy.
