Therapy Box are a great company who not only sell Proloquo2go but know it like the back of their hand and can offer very quick and accurate technical advice. Russell Smith is excellent. They do a lot of free training all over the country (that guy must live in hotels) and I really recommend them (am an s/lt)
Dd2 aged 7 uses it. She initially started with pecs and got the hang of that quite quickly but we found it very hard work making symbols etc. She gets on very well with the proloquo. Having said that we had a lot of support to get set up from communication aids specialist who made up the front page and helped us sort out folders and showed us and her TA how to use it. She uses her I pad loads now. It has helped her I think with her language development. She is now saying I want and also attempts to say more words. It is quite easy to add in pictures of new items with the I pad and I think it's pretty fab. We have also found the I pad itself great as she uses it to play games and do puzzleS as well as watching I player!
