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.

Shipping & Returns

The Microconnect USB3.1CHDMI20OP is an active optical USB cable adapter with a USB Type-C connector and an HDMI output. At 20 m length and 4 mm diameter, it enables transmission of full 4K video and audio signals between devices such as computers, TVs, monitors and projectors, providing reliable connectivity over long distances while complying with RoHS standards.

Advantages

This active optical cable supports full 4K video and audio transmission over a 20 m distance, combining USB Type-C input with HDMI output for compatibility with a wide range of devices. Its optical design reduces signal degradation over long runs compared with standard copper cables, and the slim 4 mm diameter and 0.826 kg weight make installation and routing easier in AV setups.

Suitable for

  • Connecting laptops or desktops with USB Type-C to TVs and monitors with HDMI input
  • Projector connections in conference rooms and classrooms
  • Home cinema setups where long cable runs are required
  • Presentations and events requiring stable 4K video transmission

Key specifications

  • Connector 1: USB Type-C
  • Connector 2: HDMI
  • Cable length: 20 m
  • Diameter: 4 mm
  • Weight: 0.826 kg
  • Product colour: Black
  • RoHS compliant

How to use

Connect the USB Type-C end to the source device (such as a laptop or smartphone with video output over USB-C) and plug the HDMI end into the display device (TV, monitor or projector). Ensure both devices are powered on and set the display input to the correct HDMI port. If the source device requires alternate mode or specific driver support for USB-C video output, enable that mode or install the necessary drivers according to the device manufacturer.

Recommendations

The cable is intended for indoor AV installations; avoid tight bends and sharp kinks to preserve the optical fiber. For best results, keep connectors free of dust and ensure firm connections at both ends. Verify device compatibility with USB-C video output (DisplayPort Alt Mode or equivalent) before use.
