Well, at a first glance when you get the box you may want to return it. But wait for a couple of hours and you'll find out that everything you need is in the box, but the instructions manual! If you don't find the pressure gauge guess what? The lid is flipped over. You'll learn as you go :). Packaging is really bad. Overall it works as it should for an affordable price. Seller, you need to include a manual, I mean it's a couple of bucks guys. I almost returned this. But now I love it.
