What is the opinion of Reddit about the
Graham Medical 51038 Flex Air Nonwoven Poly Pillow, White, 19″ Width, 12.5″ Length (Pack of 50)?

Inflatable pillows. Amazon. I got the 18″ x 12″ size (46 cm x 30 cm). They weigh about 1 ounce (28 grams) each, cost about US$1 each. I’ve experimented with them. I learned to put the right amount of air in it, so now it works for me okay.
