What brand of flash is good? Golden Eagle and U2?

As far as I know, overseas brands, including Kangsu, Gaoming, Ailinglong, Braun, etc ... are world-famous brands, but the prices are a little expensive. Most of them are products purchased by advertising companies for shooting. Domestic brands include: Guangbao, Jinbei, Yongjiang, U2, Hailiou, Golden Eagle, etc ... all of which are well-known brands in China. Things are cheap and beautiful.

I recommend Golden Eagle. Very good. Our photography team all use Golden Eagle.
