We have had ours for 2 months and LOVE it. My ds is 5 and begs to do it all the time. I know this will probably end at some point but for now it is great. He doesn't fight it like he did with manual pt (pat pat). We use the "quick start" setting and it is so easy. We have not had someone to our house yet, but he was fitted at the hospital and they showed us how to use it there. I hope Damien enjoys it as much as our son does.
ps Our ds doesn't watch a lot of tv, but we have special videos that he only gets to watch during his "pat pat" and that seems to help a lot (at least for us)!
