Summary: When it comes to extension cords, there are two rules of thumb: a) buy the highest quality cord (be it quality or size) and b) use the shortest possible length you can get away with it. Pros: good fit and finish; the cable is clearly marked 1 x 6.0mm^2 which corresponds to 10 AWG; Standard MC-4 connectors. Disadvantages: none. Verdict: $12 for two 3-foot cables, 5-star rating.
