Review of SS121-01, August 21, 2005By BrandyMy fiance and I bought this item because I had seen one on a video and wanted one. I chose this model with the deluxe headrest and Im glad I did. It cost at least twice as much as the other Sex Slings listed on this site, but I have a feeling it is worth the extra money if you can afford it. It was fun to use and to see my legs held up in the air with minimal effort on my part. I think this was worth what we paid and we will use it numerous times. My legs got a little sore from being in the same position for awhile, but nothing a good stretch wouldnt take care of.
