How many strokes per minute minimum and maximum?** A: This is ultrasonic and not profiler **Q: Is there any warranty?** A: I'm not sure if there is a warranty but considering the price is not even one quarter of the price on most ultrasonics l considerate a good investment are you smiling regularly with no issues **Q: What kind of air coupler is used in this item?** A: That is an excellent question.
