Is the #mrcool Dual Split Unit a #RippOff?

What happens here

This video features a creator discussing a previous DIY project where he installed a MrCool Dual Split Unit to cool his pool house. He discovered a significant discrepancy in the unit's specifications; he had purchased what he believed was a 21,000 BTU system, but upon receiving and inspecting the box, he found it was an 18,000 BTU system, rendering it undersized for his needs. The video serves as an introduction to a future 'beef video' addressing this issue with the manufacturer.
