I bought one of these last winter for a sailboat. After about 3-4 hrs of use I can say I have had no issues with the radio. The radio I bought is a version one and I see they are now selling the version 2 for less than I paid for the older version ($28.95/$22.95). Not saying they are better or worse than any other, just saying it has worked well for me. It will work for an airplane or boat(if you can use a stick radio for your boat).
