If one of these blooms near you, it's worth checking out! I can't speak to whether or not it stinks like a corpse, but I stuck my head down in there and it was certainly reminiscent of a juicy dumpster on a hot day.
Both were spectacular. Neither smelled at all.
I think the smell may only last for a short period, likely before the bloom peaks. We didn’t want to jump the gun on the bloom, so we visited a day after we heard it bloomed.
I visited the bloom my partner works with on the day after it opened, and while he attested that it was pretty stinky on opening, it wasn't really much to smell when I was there.
