Works extremely well in my open cockpit , the best unit Ive found so far for dealing with that noise level after trying several brands. It fits well in my small space and controls are large enough to be used with a gloved hand. Also comes with the best and most complete instructions of any unit we tried.

Just got an update for an older model DRE. Other one worked but the power connection got worn and was loose. Also some added features on the new model.

Works great. Replaced an older, but similar looking portable intercom in my 150 that output nothing but static. This one is crystal clear both pilot-to-passenger and pilot-to-ATC. Lots of great features with some excellent forethought put into the unit. I am most impressed with the owner's manual, though. It is written in an easy to understand parlance with the designer's personal name and email address at the end.

Appears to be well built. I like the battery box-like slots, makes easy insertion and connection for the two 9 volt batteries. I have a Piper Cub it is a noisy environment, this intercom could not handle the amount of wind and engine noise. The intercom would not allow communication (just static) between the two occupants in the aircraft, whether doors and windows were open or closed. And, using the iPhone was impossible, I could hear the person on the other end of the phone call, but they could hear nothing but engine and wind noise. I have David Clark headsets with dual foam and leather glove on the microphones. If you have a noisy environment, this is not the intercom for you. August 2017
