Several features make this my top pick. Not seen in text or picture, reverse wiring for hot and neutral is easy - grounding isn't that much. The hole in the bottom (but not the hole for the blade) is recessed, making it easier to insert than a completely flat surface. A slight bevel around the exit holes makes them better than completely flat surfaces. Fastening with screws is better than more aggressive fastening on others. Inserting the correct plugs is very smooth and easy from the start…
