First, and most important, the product works.Issue: the connector(s) to the ball(s) use a retainer clip, and being universal, they're loose (there's play between the ball and connector) compared to the OEM equipment which used a 'locking' cap - couldn't find this type in an after-market part. Does it matter? It appears that it doesn't. Only time will tell. Suggestion: put a little lubricant on the ball (not a lot) before pushing the connector onto the ball. Someone mentioned they're stiff initially, which I found to be true, but after a break-in period (lifting and closing the hatch, the stiffness subsides/disappears).
