Saw some in use in Virginia. They appeared to be unstableand impractical. The nursery manager mentioned something about trying to return them and not getting good customer service.

That's all I know....I've not used one myself.

Thanks for the follow up. I have since had follow up discussion with GrifTek and come to find out that they actually rolled out the PowerPost the week of Jan 6 at MANTS in Baltimore (I did not originally know this); therefore, I am certain that your mentioned product in Virginia is not the same. Sorry, should have known more before my original post.
