A note about the Aeris CS 3000 the entire lot were manufactured before the sale to Aqualung and prior to that sale Aeris was eliminated from the AUP line up. Also both the first lot of CS 3000 and VTX were manufactured without a beta test run. In other words they served as the beta test. I have one of the first lot VTX and I will be sending it in for a newer release which I am hopeful will resolve the screen brightness and battery problems.
