Hey There
We are actually just now doing a trial of a Vantage for my 7 year old
son. He has been on a dynavox Maestro for the last year but his
speech therapists feel the Vantage may grow with him more with the
Unity/Minspeak system. The Vantage follows a whole system of language
aquisition through motor planning (aka LAMP) that is pretty amazing
and really helps teach language and functional communication. Don't
get me wrong, I have nothing against the Dynavox company but our
Maestro has been sent back nine times in ten months for repairs which
has not allowed for consistency for him.
We have been using the Vantage for about a week on and off as we
trying to do a slow transition and he has already picked up on his
most important requests. The biggest difference I see is that with
the Vantage my son will need the use of the key guard where on the
Dynavox he did not. The classification on the Vantage also takes
awhile as a parent to learn but once you see play with it for awhile
it makes a little more sense. It really is its own language.
Hope this helps - Feel free to ask any questions and I will do the
best I can to answer
