The customer service after the sale is why the two stars. I called with a problem and was told to submit a video and wait for a reply in two business days. A video would have been useless being that the fitting didn't move. As for the product, very good grapple worked smoothly preformed as expected. The problem is the cheap flat face connecters. The female connecter failed to release once the pressure was off of it.the internals jammed and could not get to off. finally I had to cut it off and purchase good quality flat face connecters and now it works just fine.
