JieYou 5.1 head unit

Hi.
Anyone have one of this brand ?

JieYou J - 3862WH

JieYou J - 2818WH

It's on gearbest, and the price is good but no reviews, and I can't get any info anywhere...
I also see the joying JY-UL124 that seems very good by the reviews I read but it's 100€ more..

Thanks very much
