OroritoliSRAM AXS PowerLock Chain Connector 12-Speed Road Chain Link w Decal - Available in 2-Pack and 4-Pack (2)

Is it 20.99 for 2 or 4 links?

Does this make it easier to remove the chain for cleaning? How many times can I unclasp the chain before the link needs replacing?

Is this a real sram axs connector for a 12 speed flat top chain connector? or is it a after market copy ?

Will this work with a sram red 12s chain?
