The first one of these I received from Adorama did not lock into place. It should lock when it is seated. I contacted Adorama and they sent me another at no charge. The second one worked fine and it does seat well. It's not as tight as some I have owned, but I'm satisfied with it and the price is right.
I used this mount on a Meade telescope attaching a Canon 6D for some moon and planet shots. It attached firmly to the camera body and eye piece for steady shots and no worries of it coming loose. It functioned perfectly and appears to be well made.
