There have been about 30 of them go in here, I think roughly 10 have been pulled back out and replaced with conventional parlours but the rest seem to be going strong. I see Mason-Dixon farm just ordered 30 of them, judging by some of the ideas they've had in the past (like the subway for moving cows to the parlour that crashed through a block wall and killed a load of cows) I'd think that would make people hesitate for a while.
