Buying Prefabricated houses from China with Alibaba, a good deal?

[Jeffrey Anderson Gil]

Recently I received an ad showing that PTH (www.putianhouse.com) is selling pre fabricated houses and ships them from China. Does anyone have experience with this? I'm specifically interested in their light steel villas and container houses for assembly in the US for multifamily or single family houses/apartments. 

Alibaba sells them (https://putiangroup.en.alibaba...) for an approximate range of $150- $250 per Sq meter, it sounds like a great deal but wanted to ask if anyone has ever done something like this and what was your experience?
