I used their products before. Seems like they innovate faster than Jinbei and Quantum. I hope their products become more common here.
Its not just "similar" its the same product made by Godox...
I am waiting for the AD360, if not will get the AD180.
I am planning to ask my fiancee get it for me in China. Maybe can try them in China first and provide some feedback.
I will be getting a hands on when I am in China in Apr at the distributor in Shanghai. Maybe I should do a review of it and post it up.
I have checked the price and it is selling at Chinese RMB $1750 around SGD $350. Worth considering because of the battery pack.
Great! Will be waiting for your review.
