The boots are designed well, with some great materials and features. I demoed a pair at Kirkwood for a day before I committed to buying them. When I received the boots, I took them to a local shop to have the liners heat molded, and when I was cinching them up for the fitting the laces ripped in two on the lower zoneon both boots. I weigh 175lb and am not a muscle head. The RAF insert did not fit in one of the boots, and the tongues on the liners where different lengths, which was noticeable when leaning toeside. I think that someone put a lot of thought into these boots, but that the shop in China where they are built does not have the same attention to detail. Burton had replacement boots to me in just over a week from when I sent them back. When I emailed Burton about the issues, they did not respond to any of my concerns with the build quality.
I expect a lot from a pair of snowboard boots that are this expensive, I hope they deliver.
