As an Amazon Vine reviewer, I like to think that my reviews matter. Perhaps a consumer will learn something helpful, or a manufacturer will see a product suggestion. Back in February 2024, my second review on Vine was a Sarisun travel pillow, similar to this. My husband loved it and we wrote that an improvement would be a chin strap to keep his mouth from hanging open.Voila! I like to think someone at Sarisun paid attention, as here is the perfect travel pillow in our opinion! Soft, supportive, your eyes stay dark, the sound is muffled, and now your mouth will remain closed.Thanks Sarisun! Wonderful travel pillow.
