After renting equipment for face down vitrectomy surgery I decided to purchase the equipment I needed when I developed another macular hole in my retina. The rental of equipment was so pricey and insurance did not want to cover the cost. This head support was an excellent alternative. It is very high quality and actually better than the rental equipment on the Vitrectomy recovery sites. Unless your insurance company will upfront the money to rent, buy this. I will never have to rent again! Also this company was very reputable to deal with, provided fast delivery.
