First the orange plastic hose. It's not high quality rubber, it's a plastic that causes problems if you try to force pressure through it. I wouldn't attach battery clips to my car because they're made of lightweight aluminum and not the thick metal they're supposed to be. The socket at the end of the battery clip is made out of cheap, thin plastic. I thought it would be better quality. It's not high quality. The only good thing about it is that the case is made of metal and has a standard scale on it. Otherwise it's just cheap junk that doesn't last long and doesn't do its job when you need it.
