I bought the Primos Rocker last year. The top broke through and one of the staves poked through. I caught it early and I'll have my brother in law use his commercial sewing machine to re-sew the vest.
If that don't hold, I'll trash it since it's out of the warranty period. I liked the original Bucklick Creek and the Bass Pro version but my old behind has lost some natural padding over the years and I don't find them as comfortable as I once did. I'm considering trying the repaired Rocker with a bunsaver cushion and see if that doesn't put the backrest too low on my back to be comfortable.
I'll still check out the Impact when I can find one to look at in person tho. I love the run and gun utility of quickly being able to set up or move quickly. But it's not made for long sits, that's for sure.
