accuair pros and cons

I think I am ready to pull the trigger on getting it, just thought I would ask you guys for opinions. From what I have read and heard so far, it's pretty much all pros, haven't heard anything bad about the system. What you guys think??

I have not had any cons out of the ones we have installed. Easy to install, easy setup, and easy to use. They are also trying to make some interface components to incorporate them into using the factory touchscreen headunits on most vehicles.
