Safety of Chinese Stainless Steel Condensers and Still parts?

[vagabondmountainman]

I've been reading lots of old debates in the forums about the possible dangers of ethyl carbamate from copper condensers, and thinking of switching from my copper liebig to a stainless shotgun. I'm not good enough to with welding to build one, so would need to buy it from somewhere. Looking online I saw them amazingly cheap from China through Alibaba. An entire 2" reflux column with condenser with shipping is to US is cheaper than just a condenser sold from one of the big manufacturers in the US. They are supposed to be 304 stainless, but then I was wondering what the quality might be, and if there is a way to tell if it is actually 304 stainless? I'm assuming a lot of the condensers you see online in the US are made in China, as many things are these days, but I wouldn't want to buy a condenser that could actually cause worse problems with chemicals than the copper one I currently use. I'm still on the fence about wether the levels of ethyl carbamate in my product would be high enough to cause me a problem if I'm not drinking more than a 3-4 ounces of whiskey every couple of days anyway, but it seems like one less thing to worry about. Does anyone have any experience with Chinese stills/condensers? Below is a link to the condenser I was looking at.

Thanks for any feedback
