We are using
Electrical Management Systems model EMS-PT30B from
Progressive Industries, Cary, North Carolina.
My neighbor at the latest Commonwealth rally had one and when I asked about it, he gave it high marks and noted that he was sure it had protected him on at least 2 occasions. I ordered one when we got home and have used it only twice since, but I have no complaints about its design or functions.
