Review (2/5): Does the job, but fit not great
The s nozzle pro fits snug on my Babyliss hair dryer, but does regularly detach from the orchid diffuser, despite how tight you push the diffuser in to its grasp. The result is lifting the dryer and occasionally getting clunked on the head with a falling diffuser. I can usually get it to stay on just long enough to get the job down without chucking it out a window. I would recommend you just buy either a diffuser that fits your dryer or a dryer that fits your diffuser, depending on which piece you are more loyal to.
