I don't know the best forum for this so maybe Dan could decide?
I needed another electric fence energiser so I thought I'd look to see what they were making on ebay.
I was surprised to see there was a constant 'stream' of them going through, and esp after a picture of one with a corner of the label cut away, I began to wonder if they woud be all 'legal'.
Battery fence units must be one of the easiest ways to earn a quick bit of money, easy to disconnect, they flash at night so easy to find, and once away who can prove anything? (the corner that was missing did make me think of a postcode taken off).
They were making about £80+, (Rutland ESB's) - we ended up buying a new one for just over £100, seemed worth it for peace of mind and warranty.
BUT we've postcoded both new and old units, engraved in big letters and into the engraving a black indelible marker, it seemed to soak in where the surface had been opened up.
Just maybe something to think about if you have an electric fence out at night?
