i had one fore a leopard gecko once. he was stepped on at the pet shop and lost one of his eyes and messed up his leg on the same side. so i took him in. at first he had to be fed with tongs and you had to make the food move to get him to go for it. when i got this it made feeding my handicapped friend a lot easier.
That's great that it helped with your gecko. I was just amazed that someone would think up such a thing. Which is probably why they're not paying me to do their R & D.
