Harper ★★★★★

Sturdy little thing—the 3/8" female side threads on clean and snug, no wobble once tightened. Saved me from buying a whole new head just to mount my camcorder.

Daniel J. ★★★★★

Finally got my quick-release plate to fit on an older tripod head without any wobble—the brass threads on this adapter feel solid and catch smoothly.

Avery B. ★★★★★

This little adapter solved my problem of mounting a small monopod head onto a larger tripod base, and the threads fit perfectly without any wobble. It's small enough to keep in my bag as a backup for odd setups.
