The uClan Ustym 4K OTT Premium is the top-tier “pure streaming” model in the Ustym lineup. While it lacks the physical satellite/cable tuners of the “PRO” model, it compensates by offering more flash storage and a superior remote control, making it the preferred choice for high-end IPTV and OTT users on enigma2.net.

## Full Review: uClan Ustym 4K OTT Premium

The “Premium” tag refers to two major upgrades over the standard OTT X: a larger 8GB eMMC flash (doubling the space for Multiboot) and the inclusion of the uClan Premium RCU v4.0—one of the best remotes in the Enigma2 world.

## 1. Hardware & 4K Performance

Under the hood, the Premium maintains the elite Huawei Hisilicon Hi3798MV200 quad-core processor found in the PRO model, giving it a massive 15,000 DMIPS.

• Memory: 1GB DDR3 RAM paired with 8GB eMMC Flash. This 8GB of storage is the game-changer; it allows you to run a full Dual-Boot setup (Denys_OS + Enigma2) while still having enough room for 3-4 additional image slots in Multiboot.

• 4K UHD: Supports 4K @ 60fps, HDR10, and HLG. The video quality is exceptional, particularly when using the Chromium web browser or Stalker portals.

• Networking: 10/100 Mbps Ethernet. While we would have loved to see Gigabit here (like the PRO), 100Mbit is perfectly adequate for even the highest bitrate 4K OTT streams.

## 2. The uClan Premium RCU v4.0

The biggest “Premium” feature is the remote control.

• Tactile Feel: It uses high-quality rubber with a velvety finish. The main directional buttons feature a distinct “soft click,” while the rest are silent.

• Programmable: It includes 4 programmable buttons at the top to control your TV’s power, volume, and source, eliminating the need for two remotes.

• Virtual Mouse: Features a dedicated virtual mouse function, which is essential for navigating some non-optimized IPTV apps or web pages.

## 3. Dual-Boot Software Ecosystem

The Premium gives you the best of uClan’s software development:

• Denys_OS: This is the default IPTV OS. It’s incredibly fast and offers a “seamless” TV experience. It supports Stalker, Xtream, and M3U with a professional EPG and picon integration that often rivals Enigma2 for ease of use.

• Enigma2 Multiboot: It fully supports the OE-Alliance ecosystem (OpenATV, OpenPLi, PurE2). Because of the 8GB flash, you can experiment with different images without worrying about running out of space for picons or heavy skins.

## 4. Connectivity & Design

The box is compact (110mm x 110mm), featuring a sleek, polished finish.

 

• Hidden Install: Comes with an External IR Receiver so you can hide the box behind a wall-mounted TV.

• Ports:

  • 2x USB 2.0 ports.

  • 1x TF (MicroSD) card reader for extra storage.

  • HDMI 2.0a, Optical SPDIF, and AV Mini-Jack.

• WiFi: Built-in WiFi support (typically requires a USB dongle, though some regional versions vary).

## Final Verdict

The uClan Ustym 4K OTT Premium is for the user who has moved entirely to streaming but refuses to give up the power of a Linux Enigma2 box. Its large flash memory makes it the most flexible “streaming-only” box uClan has ever produced.

Best For: Users on enigma2.net who want a “smart” streaming box with pro-grade remote control and enough space to run multiple Enigma2 images for IPTV management.
