Sorry, it's more and more difficult for me to access websites outside of China.
We improved YN-E3-RT and YN622C-TX in November, 2014. The factory began to assemble the new version in December. If the date of manufacture is later than Dec/15/2014, it should be the latest version. There may be some existing stocks of old version depends on the sellers.
Hi liangcc,
Is this also the same for the YN622N-TX or did that one not need the improvement?
