Your wrists move through impact in about a fifth of a second. That's why you can't feel what they did, and why "that one felt better" is usually wrong. Wrist-X clicks the instant your wrist crosses the angle you set, anywhere from 0 to 70 degrees. You hear it at the top, you hear it at release, and you know what your hands actually did on that swing. 99 days to try it. If your contact hasn't changed, send it back.
