I bought the trinocular head and an adapter for Sony DSLR adapter, hoping to build up an Olympus system. That, however, didn't work out and thus letting this go. As far as I can tell, the head is in good shape cosmetically.
The thumb grip on the right side of the head falls off but pulling the lever in and out is not affected. I don't have a way to test the head otherwise.
