Anyone used a fence mender?

I have a not terribly old fence (6ish years) that was either not dug deep enough or allowed to set so it's been leaning for a while. We dug around it and poured new concrete 3ish years ago and it helped a bit. The winds of the last few weeks have it leaning a lot. I saw this fence mender things on TikTok and wonder if anyone tried one? Ideally I'd love to get 1-2 more years out of the fence before biting the bullet and replacing the whole thing.
