Thick enough to be certain it can carry the electric load without a concern and long enough to reach plus the grey color has it blend in well with surroundings. Highly recommend it.
[This review was collected as part of a promotion.] I love the flat angle plug so it can fit into tight spaces. And the slide-to-lock safety covers are great for keeping the unused outlets unexposed which makes it safer. The hook feature is also unique & could be useful for certain setups.
