The Tekonsha 90160 Primus IQ Electronic Brake Control is a solid choice for those in need of a reliable trailer brake controller. One of its key strengths is the Plug-N-Play feature, which allows for easy installation with compatible T-connectors. This is a significant benefit for users who may not be very experienced with wiring or installation, as it helps simplify the process. The digital LED readout adds another layer of convenience, providing real-time diagnostics and making it easier to monitor performance.

This brake controller boasts good performance with its proportional braking feature that works in reverse, enhancing safety while reversing a trailer. The Boost feature is also a plus, allowing for adjustable braking power for different situations and improving control, especially for heavier loads.

However, there are some drawbacks to consider. The T-connector required for installation is sold separately, which could be an additional expense and a slight inconvenience for users who might expect a complete package. Additionally, while the self-diagnostics feature is useful, it may not cover all potential issues, leaving some users uncertain about specific problems. The dimensions and weight of the device make it compact and lightweight, which is great for minimizing extra bulk in your vehicle. The Tekonsha 90160 Primus IQ is well-suited for casual to moderate trailer users who value ease of use and reliability. Its strong performance and user-friendly features make it a commendable choice, though users should be prepared for the additional purchase of installation accessories.

The Tekonsha 8508220 Brake-EVN Proportional Electric Trailer Brake Controller is designed for trailers with 1 to 4 axles, making it a great option for a range of users, from occasional travelers to more frequent haulers. One of its key strengths is the proportional braking system, which adjusts the brake power based on how hard you apply your tow vehicle's brakes. This feature enhances safety by providing automatic and smoother braking in various situations. The inclusion of an internal inertia sensor is a notable plus, ensuring that the braking response is aligned with your needs.

Installation is made easy with the Plug & Play port and removable electrical connector—this means that users can set it up without extensive technical knowledge. Additionally, the easy-to-read LED display provides real-time diagnostics and alerts, which can be especially helpful for monitoring the system while driving. The manual control lever is another useful feature, allowing for direct application of the brakes when necessary.

While it boasts compatibility with a wide range of vehicle brands, the vehicle-specific wiring harness required for installation is sold separately, which could incur additional costs and complicate the setup process slightly. Some users may also find the display information to be minimal in terms of detailed diagnostics.

Vehicle-specific wiring harnesses are sold separately, which could be an added expense. With a compact size and easy installation, the Brakeman IV is a convenient option for those new to trailer brake controllers. One potential drawback is the time-delay mechanism, which may not provide the instant response needed for heavier towing applications.
