The picture's don't scream good quality to me!!
I'll grant that Chinese turning tools do not have a great reputation. Those £20 sets on eBay are truly awful. However some items they make are worthwhile, the Chinese Quangsheng Planes have made a fantastic name for themselves.
Even if it's not great HSS, it should be better than Carbon Steel, which most of my SRGs are made from.
There is only one way to find out, buy one and try it.
