Aiersi Guitars is the main house brand name but they are also the OEM for Koa Pili Koko, (and they also sell them direct, having dropped the Koa so as just Pili Koko, they may even own the name now?), Kamoa, (another brand they may even own, I'm not sure?) and a lot of others I won't list here unless I see some firm evidence; (plus they make some ukulele kits that I suspect are purchased by third parties outside China, assembled and branded as locally produced instruments - again though I can't prove it). 

I have also seen their output branded as Berkeley, Laiersi, Bali Hai, Rainie, Headway, (nothing to do with the Japanese firm Headway Guitars), and there may be others. Whether they own the brand or its more OEM I don't know. Even without official acknowledgement though, it looks like they are OEM for a number of more famous and prestigious Ukulele brands too.
