Query: Underpowered, lousy

We received a pair of the T5820s as a gift. Thought these would be an upgrade to our old FRS radio. It was a downgrade! The 5-mile rating is a joke. The old FRS radios way out-perform the 5820s, and are more compatible with other radios.Pros:-Locking Menu Button-DurableCons:-Range-Compatibility with other radios.
