I have been using Reptile Basics panels for about 6 years give or take. The original plug design with the cord that was attached was great imo, required a minimal hole drilled to install the panel, and didn't cause any headaches as attaching the plug end was very easy. The change they made with a cord that is detached was a decision that I didn't particularly care for, beyond requiring a larger hole to be drilled, the way the cord attached to the panel was not terribly stable. Fast forward to yesterday when I received my first new RHP from RB in a bit and I'm pleased with the inclusion of a new support clip being incorporated into the design. My worry about an exploring animal wedging the plug loose is no longer an issue. Glad to see they are continuing to refine the design.
