I purchased 2 of these back scratchers. One for my mini donkey and pony stable and the other for my Nigerian dwarf goats. Everyone is using them and seem to be enjoying them.
I put two up on the opening (around the front post in the door way) of her shelter. It was used soon after and has continued to be used , probably dailly. They were difficult to wrap around the post , as the sheets are stiff, but I was able to do it by myself. The screws are low quality and I would ask for "star" screws but it did come with washers as well as screws. The product knobs are quite bulky and since the sheet doesn't wrap around flush ( because it's too stiff) it does offer an adequate surface .
