The problem with these (I bought 2) is the 'T-shaped' base is useless against even light winds. It will topple over very easily. You literally need to tie several guy lines to the post (like pitching a tent) and secure the lines with big long camping stakes to steady it. By the time you're done, you're worried about people tripping over your guy lines! The T-base will work if you bury it in concrete, creating a permanent base for the post to slide onto.
