Review on 😌 Ultimate Comfort on the Go: TREKOLOGY Inflatable Neck Pillow for Travelers by April Daniels

Lots of 1 star reviews complain that you can't inflate it without deflating. But that's because they didn't read the instructions on the sticker on the pillow: (To inflate, open the outer valve and press the black button to the UP position to close the air outlet. Inflate with your mouth. To adjust the firmness, press the black button halfway down. To deflate, press the black button to the DOWN position to open the air outlet.) With the small black button UP, it holds the air. What I'm not sure about yet is how long it will last before leaking. But I need an inflatable for the trip because I just can't carry (and lose) one more item (a bulky neck pillow) on the trip. Also, on some trips, like hiking, I can't take a regular neck pillow at all.
