They are FANTASTIC for camping
I honestly haven't the slightest clue why other people rated this product poorly. Did they not understand what they were buying? To be clear, this is the SMALLEST INFLATABLE PILLOW currently on the market. It comes with a straw that you use to blow it up and deflate it (you could use a regular straw too). This are surprisingly durable- you can sit on them- and the air will not come out. They are FANTASTIC for camping, airplane/train rides, etc. They are designed specifically for ambulances and hospitals where space is a premium. Again...I just am so preplexed by other reviewers. This is exactly what I was looking for, used it on a 3 month backpacking trip in Europe, and everyone thought it was the coolest thing!
