What to say? This is the industry standard mains power connector for a reason. Good solid construction, easy to use, and locking to avoid accidental disconnection. The cosmetic design of this connector has changed recently (yellow release clip) but it is 100% compatible, and to my eyes even better built than before. Note that the grey connectors for taking power FROM a rack only - the equivalent of a male IEC connector on a cable.
The Real McCoy, if only they had silver locking tabs!
As mentioned in my review of the NAC3 FCA I'd prefer that I'd got connectors with silver locking tabs rather than yellow.
However, how the connector looks is far less important than how they work. I like PowerCon very much because they lock, giving a feeling of confidence that they can't fall out and leave you in trouble!
These are original Neutrik connectors, so you are getting the best there are AFAIK; no risk of compatibility issues.
