Hi Johnson,
No trouble at all :)
They are legit as a company but I'm not too sure about their product's authenticity. You see the company's registration info shows that they are based in Shenzhen although their contact us page will show that they have an office in HK.
Again, the likelihood of bootleg versions is very high knowing that the company is actually base in Shenzhen China. Also, there are mixed reviews about the site, most of which are negative (unfortunately).
For your reference, below is the link to their whois search result:
