This little seat is OK. It's main advantage is definitely its small size. When folded it is only about a foot long, and easy to carry in a bag, backpack, or your hand. It's case has a handle if you want to just carry it that way. It is incredibly small and light.It doesn't come with any instructions. A couple of the legs are a little sticky on mine, so I was afraid I was missing some secret to unlock them when opening them up, but eventually got them. There really is a secret to closing the legs. I can't believe they don't have any instructions to tell you. You have to fold the chair first with the legs extended. Once the legs are all lined up, you can easily collapse them. If you try to collapse them before that, you can't. There is not button, you don't need to twist, just fold the chair so that all of the legs are aligned.The extensions on the legs are covered in light oil. I understand that it helps them slide in and out, but I do;t think it is very practical. The first time I opened them, I got oil all over my hands. Once they are open, that means the lower half of the legs are completely covered in oil. That's not great, as dust and dirt will stick to them.Once opened up the stool is small and low (about 14" high), but I found it surprisingly comfortable. It will need a firm surface to be set up on, but if you don't mind sitting down that low it is really not bad.This is a decent little stool whose main benefit is being extremely small, light, and easy to carry. Surprisingly comfortable (to me, at least) for its size. It's not perfect, but if you want something small enough to keep with you it is really not bad.
