“I really wanted to love this jug, but I don't. The rubber seal ring fell out after only a week of using it and it is absolutely impossible to put back in. It won't stay. Now the jug leaks whenever I try to use it. I also purchased the straw to use. Well - that is junk too. The white plastic tip doesn't stay on tight enough to drink through it. Save your money and keep looking. This jug and it's accessories are poorly made and don't work”
