Bests & Worsts Reviews from Amazon

Not sure why this one is more expensive. I bought ALL the pillows in this shape so I could compare them. This one is identical to the ones by Simptech and HAOBAIMEI. Clearly the same manufacturer. Maybe it's the money-back guarantee that makes this one worth more? The only one of these pillows that was different was the HOMCA one, but the differences are tiny. They seem to all be the same shape, height, width and material. I'll update this review if any of them lose air overnight. Assuming no other differences emerge, I'll probably return this one and keep one of the cheaper ones.
