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.

With Android 14 OS, iiSignage² (CMS), iiControl (DMS) and iiShare , plus EShare (Wireless Presentation) features, this display offers a straightforward user experience, making content creation, management, and sharing a breeze. WiFi enabled, the display is ready for remote content delivery using your network or you can choose to utilise LAN control.

Android OS

Thanks to Android OS, you can easily customize the display to your needs by installing applications directly to it.

iiSignage²

iiSignage² is our digital signage content management platform to easily show and control your content and to manage your displays in a secure way. The Content Management System (CMS) gives you total control of your messaging and advertising remotely and safely.

iiControl - Device Management System

iiControl provides organizations with a convenient and fast unified management solution for terminal equipment, builds an efficient and real-time equipment management system, helps digitize the campus/office estate environment and makes device management ultra convenient. iiControl DMS is committed to maintaining compliance with GDPR.

Signal FailOver

FailOver is a feature which automatically detects input sources. When there is no signal on the default input it will automatically switch to the next available input. FailOver allows customers to prioritize a number of inputs (incl. Browser, Media Player and Custom) and ensures your content is always actively displayed, assuring active content at all times.

How to use

Install the panel securely using compatible VESA mounts and connect to power. Configure network access via Wi‑Fi or Ethernet to enable remote content updates. Use the preinstalled Android platform and iiSignage²/iiControl apps to create, schedule and manage playlists or mirror content wirelessly via iiShare and EShare. Adjust display settings such as brightness and orientation from the on‑screen menu to match the installation environment.

Recommendations

For reliable long‑term performance, operate the display in a ventilated environment, avoid direct exposure to sunlight, and use the supplied content management tools to schedule regular content and firmware updates. When deploying in bright areas, consider calibrating brightness and contrast for optimal legibility.
