Huh, I would swear I posted a reply to this yesterday, maybe I hit the close window button instead of submit
Anyhow...
The Premier type electronet is wonderful IF you respect its idiosyncrasies; it is worse than useless if you don't or if they don't fit with what you're trying to achieve.
You need to have a good charger hooked up to it (it requires more charger per length of fence than other kinds of electric fencing) and like any electric fence you need to install things correctly and monitor every day or two with a good digital fence-tester (the neon-lights ones are way too inaccurate) to ensure it keeps enough charge.
You need to be prepared to move it and mow (or spray herbicide, but I do not personally advocate that at all) where it goes WHENEVER the grass starts to grow more than a few inches high, which can be rather frequently in late spring or early summer. THis does not take long at ALL -- all ya do is pick up each stake, doink it into the ground a few feet to the left, run the mower where the fenceline was, then doink the stakes back in where they belong -- but you do have to DO it, or the fence becomes useless.
I highly recommend tying back at least the corners, also some run posts if it is a long fence, so strong winds don't flatten the fence or make it sag so much it grounds out; and the fence is essentially useless during times of ice or snow.
It is really intended as a growing-season fence for well-maintained rotational grazing purposes; for that, it is GREAT. As 'set and forget', it is useless
JMHO, good luck, have fun,
