Features & Capabilities

The CURT Echo (51180) is a Bluetooth-enabled trailer brake controller that sits between the vehicle and trailer 7-way connector and syncs with the Smart Control app on your phone. Using the app, you can adjust maximum braking power and sensitivity and view diagnostic information such as overload conditions and trailer-disconnect errors. A manual override button lets you activate the trailer brakes as needed for added safety.

Its compact plug-and-play design makes it highly portable and transferable between vehicle-trailer combinations. The Smart Control app stores up to five user profiles with personalized settings, and the CURT Echo continues to function even when the app isn't open, using the last-selected profile to determine braking aggressiveness.

User Reviews

Users largely praise the Echo's ease of use, quick setup, and reliable braking when it works, along with useful profile/settings for different trailers. However, many report serious downsides: frequent connectivity problems, unreliable performance, and brakes sometimes engaging dangerously or unpredictably. Repeated app updates force migration to a new app with mandatory registrations and location sharing, causing frustration and loss of functionality. Also, users want CarPlay/Android Auto support and hands-free control. Support is inconsistent. Overall sentiment is mixed leaning negative due to safety and reliability concerns, despite some positive experiences.
Pros
  • Ease of use and quick setup when the system is functioning
  • Reliable braking and good performance for trailers when connected
  • Profile/settings customization makes it convenient to tailor braking for different trailers
  • Plug-and-play installation and simple integration with compatible tow setups
  • Overall value as a helpful braking controller for towing
Cons
  • Frequent connectivity issues and unreliable performance; disconnects or inability to reconnect
  • Safety concerns with brakes engaging unpredictably or locking up, described as dangerous
  • Forced migration to a new app with mandatory registration and location sharing/privacy concerns
  • Lack of CarPlay/Android Auto support; needing to look at the phone while towing
