I needed extra reach to position my panels away from the shaded side of the house, and this 30 ft HPP+ extension cable did the job. The 10 AWG gauge and 40 A rating feel appropriately heavy for the current, and the male-to-female HPP+ connectors click together solidly with no wiggling. I use it between my HPP+ combiner and Yeti PRO 4000 setup, and everything stays consistent. It is 4.7 lbs, so it is not flimsy, but coiling it up for storage is still manageable. Just remember it is not compatible with Yeti X Line.
