I've not heard of the Light Writer SL5, but try the Trace Center at the U. of Wisconsin. As a matter of fact, those of you with CD Roms can get all sorts of info on adaptive communication and other devices via a CD Rom that the Trace Center offers. I don't know the cost as it has probably gone up since I last bought one, but do look up the center on the internet. For all I know the info could now all be available over the internet. Also, use the word "Rehabilitation" and see what you get. It's just a thought. And it's possible that they have reviewed this Light Writer SL5. It sounds most interesting. Good luck to you in finding more information. Sincerely, Barb Brock [log in to unmask]
