We've demoed a few models and recently started the purchasing process for a set for our aircraft. The ones we're ordering will be self-standing removable equipment (Class 2 EFBs)
Our parent company has fully integrated hard mounted EFBs (Class 3)... I've played around a bit with them. Nice to have, but the equipment is a bit out dated since they had them installed about two years ago.
Have any specific questions?
