Bought before our last trip. After the first two dive my wife's wasn't retracting. By the end of the third day mine wasn't retracting either. I was able to get them freed up eventually, but I don't think I would recommend them to anyone. I don't think this is typical for other brands.

This is not really typical for this Retractor. We sell thousands and do not hear complaints from other customers. However, we do get a few calls every now and then where they did not realize there is a small pin you have to press in order to trigger the retraction.
