From what I can tell is they sold out completely of the old version so they can't send out a replacement. Then the new version has been delayed over and over again because of manufacturing problems. I think they wanted to switch back from Asia to the USA for building them, but I don't know if they achieved that. It's insanely frustrating for sure. A refund should be an option for everyone with an RMA all along.
I once kited with a guy who I found out later is the owner of the company. He sited the problems Samsung has had with the Note 7 and said, "only make as many as you are willing to take back". Meaning, if there is the smallest problem at the factory, everything is lost. Maybe they are intensely testing the new one(?)
When riding with him, he was on a pole board and I was boosting a 9m. I saw a ramp coming in, hit it, then looked down to see him right below me. I first thought I might hit him. Then he front flipped below me. When I didn't land on him, I thought he was going to be pissed. But talking to him later he was like, "I saw that ramp coming and thought, he is going to boost, that's what I'd do." Seriously cool dude there.
BTW, I do sell Xensrs but have two on RMA right now.
