Abous Us

4Tron Enterprise, Inc (formerly Nor Systems, Inc.) is a privately owned company, with 20+ years of experience in the off-lease IT/computer market.

In recent years, we are switching to service online community. Statistics of various resources shows we made 99% of tens of thousands of customers happy in the past 20 years, as of 2018.

It is not an easy task to run e-business due to thin-profit. We did work hard, and will continue to focus on our service.
