LOL 200% on what Kasey said
I am also a C4/C5 incomplete 4 complete 5 high-level quad & I only use the QS as my gaming controller
I am a big fan of the mediaeval hack and slash sword fighting style games as it's a great way to introduce yourself to the mouth control with the QS a.k.a. quadrstick the witcher 3 is a great game to play but not around children as there is quite a lot of adult content :-) :-) skyrim is also another one I'm a fan of building yourself up to be a champion :-)
I love Project cars as you can configure the game settings itself to make driving great fun just with the mouthpiece,
I am playing using the PS4 I love the QS so much I bought a couple of extra spare controllers as I have a little bit of funding left over last financial year.
Like I said to Fred and others on the forum the QS has enabled me to be a gamer who can now compete on an equal footing with able-bodied people in the gaming world, no more just the ever faithful sidekick watching my brother or nephews play, I can do it whenever I like myself without having to wait for someone to come over to play games :-)
having MD you will have no problem playing any of the games available as it takes very little breast capacity to do it :-)
If you decide to play the witcher 3 or skyrim and need some pointers just drop me a line happy to help
To be honest I have been a bit lazy in learning how to program the CSV for different games and making it easier on myself LOL, but the good thing is a lot of games you can get away using the default controller settings :-)
The only annoying thing with the PS4 is it has the touchpad and you really need to use it in certain games to access certain features, which is easily circumvented but just the pain to go through all the settings to set it up
I know you'll love it once you start using it & welcome to the QS club :-) which I have found to be a great bunch of people ready to help out in any way they can with shared knowledge
Cheers from down under
