Build Quality and Construction
The Gang Box: A Solid Foundation
The metal gang box represents the strongest component of this kit. Users consistently praise its substantial construction, noting the heavy-duty feel and robust mounting options. The galvanized threading and weather-tight seals demonstrate attention to detail in the housing design. The box provides adequate depth for most standard installations, though some users working with larger wire gauges or requiring wire nuts inside the box report tight quarters.
The mounting system offers flexibility with both surface-mount and recessed installation options. However, several users note that the rear mounting tabs may require modification for certain siding types, particularly when retrofitting existing installations. The inclusion of mounting hardware is appreciated, though the self-tapping screws occasionally prove challenging with harder mounting surfaces.
Cover Design: Thoughtful Engineering
The weatherproof cover showcases intelligent design features that address real-world outdoor electrical needs. The clear polycarbonate construction allows visual confirmation of outlet status while providing robust protection against the elements. The removable cord slot at the bottom enables in-use protection – a crucial feature for applications requiring continuous power connection.
One standout feature is the adjustable mounting orientation. The hinge pin can theoretically be removed to switch between vertical and horizontal mounting positions, though multiple users report difficulty with this adjustment. When the pin removal works as intended, it provides valuable installation flexibility for different mounting scenarios.
The gasket system around the cover perimeter provides effective moisture protection when properly sealed. However, some users report that the door itself lacks adequate gasket protection, potentially allowing moisture infiltration during severe weather conditions.
The GFCI Outlet: The Achilles’ Heel
Widespread Reliability Issues
The most significant and concerning aspect of this kit is the GFCI outlet reliability. An alarming pattern emerges from user feedback, with numerous reports of dead-on-arrival units and premature failures. Conservative estimates suggest that 15-20% of units experience GFCI problems, ranging from complete failure to intermittent operation.
Common failure modes include:
- Dead on arrival: Units that never function despite correct installation
- Failure to reset: GFCI trips and cannot be reset despite proper wiring
- Premature failure: Units that work initially but fail within months
- Inconsistent operation: Intermittent functionality that may appear to work temporarily
Installation Challenges
Beyond reliability concerns, the included GFCI presents several installation challenges. Users working with 12 AWG wire (standard for 20-amp circuits) report difficulty with wire connections, as the terminal screws appear designed for smaller wire gauges. The terminal design, with recessed threading, complicates proper wire installation and may require longer screws for secure connections.
The self-testing feature, while conceptually valuable, adds complexity that may contribute to reliability issues. The LED indicator system, designed to provide continuous monitoring of GFCI function, appears to be a point of failure in some units.
Quality Control Concerns
The pattern of GFCI failures suggests potential quality control issues in manufacturing. Multiple users note that replacement with name-brand GFCI outlets (such as Leviton) immediately resolves functionality problems, indicating that the issue lies specifically with the included GFCI rather than installation errors or electrical system problems.
Installation Experience
Ease of Installation
When the components function as intended, installation proves straightforward for users with basic electrical knowledge. The complete kit approach eliminates the guesswork of component compatibility, and the included instructions provide adequate guidance for standard installations.
Users appreciate having all necessary components in one package, eliminating multiple trips to hardware stores. The mounting flexibility and clear cover design contribute to a professional-looking finished installation.
Common Installation Challenges
Several installation challenges emerge consistently in user feedback:
- Box Depth Limitations: Tight quarters when working with larger wire gauges or when wire nuts are required inside the box
- Mounting Hardware Issues: Self-tapping screws may strip or break during installation, particularly with harder mounting surfaces
- Hinge Pin Adjustment: Difficulty removing the hinge pin to change cover orientation from vertical to horizontal
- Ground Screw Access: Limited accessibility to the ground screw within the box configuration
Professional vs. DIY Installation
While many DIY users successfully install these units, several report calling in electricians after encountering GFCI functionality issues. Professional installers appear to have mixed experiences, with some praising the complete kit concept while others express frustration with the outlet reliability.
Weather Performance
Effective Moisture Protection
When properly installed and sealed, the housing and cover system provides excellent protection against rain, snow, and humidity. Users report successful performance through various weather conditions, including wind-driven rain and extended exposure to outdoor elements.
The in-use cover design allows for cord connection while maintaining weather protection – a significant advantage over basic outlet covers that must remain open during use.
Long-term Durability
The metal gang box and polycarbonate cover demonstrate good long-term durability in outdoor environments. Users with installations lasting multiple years report continued weather protection and structural integrity of these components.
However, the lack of a proper door gasket on some units allows moisture infiltration that can cause GFCI tripping, even when the outlet itself remains dry.
Value Proposition Analysis
Cost Comparison
The kit pricing often provides savings compared to purchasing components individually, particularly when compared to big-box store prices. However, the value proposition diminishes significantly when factoring in the likelihood of GFCI replacement.
