I've been using it for years. I can see they made some changes to a few units because the one with a push pin in the middle that separates them a few are people hands our fingers push a little harder breaking that pain in the middle and if you don't have anything that can be repaired or repaired you have nothing to do if they could replace it where you can fix it yourself, that person gets easier when it breaks mine but I've seen one too , they have a threaded connection that connects both hoses. I think I like this one, I might buy it in the future
