I think is a quality wire and affordable
Size: 2AWG 15FT + 15FT, Color: Red + Black
The wire is excellent; its thickness feels appropriate, and it appears to be high quality. I've installed it on my PV array, which delivers over 40 amps DC, and the wire handles this load well. MC4 connectors are not included but are pre-cut for easy installation, and I encountered no problems.
