Wishon was a top notch company, I can’t speak to it now, but I had the 870ti irons, I picked up second hand, somehow two had a rattle in the hosel and one the weld on the face was suspect, contacted them to find a remedy and to ask about the weld, they replaced all of them with new heads, no charge, no question. Kind of surprised me, most companies warranty ends with the original poster. I think that set might have been cursed though, I put a new set of the Apollo hump shafts in them and the shafts all bent at the hosel, in one practice session/ a round that I had to play with them because it was a work outing. I proceeded to bend the 7 iron shaft of the next set of iron shafts to the point of noticing it before pulling that set and finding more bent tips. I never did reshaft them.. I did however stop buying Apollo anything as they didn’t want to warrant the replacement set which was their high end shaft at the time. They tried to claim I was “abusing” the clubs, there was nothing to indicate that and the tips were bent all in the same direction, but it was a good pissing contest to get anything done.
