Every metal feeder I have ever had is nothing but trouble at least where I live.
The problem I have with metal is that condensation easily forms inside of it due to temperature differences between the outside and inside of the barrel.
It then runs down the inside, into the corn, and they clog up horribly.
I have been running about 15 poly feeders for 20 years with no issues other than a timer messing up from time to time.
I had 5 hanging feeders with funnels one year, every single one clogged. Tried again only filling them halfway, still same issue, I sold everyone of them and will never buy another.
I did have 2 tripods get wrecked a couple weeks ago.
I am going to try getting 10 foot long legs in thicker gauge steel, that don't come apart, to get them higher.
Then I am going to get 4 foot long rebar and drive it down around each leg about a 1.5 feet from where each leg hits the ground.
I then am going to get wire and wrap it around the rebar a bunch of times really tight.
If that doesn't work, I will probably scream and holler a bunch of four letter words and create some new ones. lol
