I have one of the ceramic ones that I got from Sead and it is amazing. I get a ton of compliments on it. It's stainless however, I've never seen the other one on the site you linked
...don't go near the cheaper ones in this case, they are rubbish. ....Also that site above..."groupbuyluxury" just another dodgy internet replica site, nobody has any idea what you'll receive once you part with money.
...also saw this on watcheden. wouldn't trust this build or the site. The bezel numbers are all wrong. I'm pulling the trigger on the 1:1 version next week. Similar to the sead offering...also offered at PC.
