I've seen spotty reviews on the technology, but I had a need at home and on several client sites for a bridge option the tech offered, so I decided to try it out. After many hours of isolating circuits, disassembling the service box to determine the bus bar phase layout, etc. I gave up on the units due to intermittent and slow connectivity. The software that came with them was clunky, slow and resource intensive and did nothing to assist with connection diagnosis. After two days, I reactivated my wireless bridge setup (WRT54GL w/DD-WRT; works like a champ except when the microwave is on.)
