Mate of mine had one for years, replaced it with another. Not the one referred to in the OP though. Although it was a big spend for him, he wouldn’t spend that amount. Big time motorbiker, went to a number of rallies every year. IIRC, the tent inflated using CO2 capsules, like the ones used in 2nd Wind pumps. I don’t think CO2 is as subject to ambient weeather pressure fluctuations (could be wrong though). Pretty bulky, but up in under a minute. Maker may have been Khayam. Anyway, after around 15 years of pretty regular use and pretty irregular maintenance, he replaced it with the same one.
No idea what pitching it was like in bad weather, but he loved it.
