Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

Problem with an order right now? Write to [email protected], [email protected] or [email protected] — answered the same business day. The letter also lists our group and store owners' contacts.
Know our brand? Leave an honest review, send us a screenshot, and pick a free gift — shipped free of charge within 1–2 business days.
Pay the courier with no extra fees.
Need help? DistriNode AI can handle any task on our site.

Connect to a Gigabit Ethernet network through your laptop’s USB-A port using the Gigabit SFP of your choice

This USB 3.0 to fiber-optic converter lets you utilize the USB 3.0 (Type-A) port on your laptop or tablet to provide a secure fiber network connection. Windows® and Mac compatible, the network adapter provides a Gigabit Ethernet (1000Mbps) optical network connection for portable laptops or tablets, or systems without expansion slots.

A flexible solution with an open SFP slot

The open SFP slot enables you to use your preferred SFP transceiver module to meet your networking needs - use an SFP with your desired wavelength, distance, and connection type to achieve an efficient network solution. (SFP sold separately.)

Secure fiber-to-the-desk connectivity

This USB to fiber-optic converter provides reliable fiber connectivity while protecting your network from problems with electronic interference - a common issue with copper Ethernet networks. Fiber-to-the-desk connectivity (FTTD) maximizes network security, reducing the risk of data leaks for sensitive information, without compromising network speed and reliability.

Easy portability

Compact and portable, this USB 3.0 to fiber-optic converter is powered directly from the USB port.

Plug and play

Get up and running quickly. The USB to fiber-optic converter supports certified drivers for Windows, Mac and Linux®. Once the adapter is plugged into a USB port, you simply install the drivers and the adapter is ready to transmit over a fiber network.
