Personally, I find the video incomplete. It sounds like IronMan tried to engage the owner but he wasn’t interested in providing them information. If I were them, I’d probably be done there too. I wish we had a write up with the actual facts. Consequently, if the IronMan springs are coming, I’d wait to get too worried as I’m not convinced you won’t be okay or that IronMan won’t back their product up. That said, no real reason not to go with the Dobinsons. Personally, I very much dislike IronMan’s vivid green.
