Trabaja muy bien, lo único que no me gustó, es que el material con el que está hecho, es muy frágil, por lo demás hace buen trabajo

I had a few containers of DEF and was worried about them being past the expiration date so purchased this item and was relieved to find all containers still read “Good”. Well worth it!
