Casiris Tech Omnistar L80 Hands-On Review: 1080p Projector Stumbles Across the Finish Line

The Casiris Tech Omnistar L80 is a 1080p projector that aims to bring the big-screen cinema experience to your living room. With its compact size, Android TV operating system, and a range of connectivity options, it promises to be a versatile and user-friendly device. However, in this hands-on review, we will explore the performance and features of the Omnistar L80 and discuss how it falls short of expectations, ultimately stumbling across the finish line.

Design and Build Quality:

The Omnistar L80 boasts a compact and sleek design that blends well with modern aesthetics. Its dimensions of 28.71 x 28.96 x 18.03 cm (11.3 x 11.4 x 7.1 in) make it relatively portable, allowing for easy placement and transport. However, the build quality feels somewhat lacking, with a predominantly plastic construction that may not inspire confidence in its durability.

Display Quality and Brightness:

With a maximum resolution of Full HD (1920×1080), the Omnistar L80 delivers crisp and detailed images. The image size can range from 40 to 200 inches, allowing for flexible viewing options. However, the brightness level of 1,500 ANSI lumens falls short when compared to other projectors in the same price range. In well-lit environments, the image may appear washed out and lack the desired vibrancy.

Performance and Connectivity:

The Omnistar L80 is powered by a quad-core Cortex-A53 CPU and an ARM Mali-G31 MP2 GPU, accompanied by 1GB of RAM. While this setup is sufficient for basic multimedia playback and streaming, it may struggle with demanding applications and multitasking. The 8GB of storage is limited, especially considering the device’s Android TV operating system, which may require regular app updates and installations.

Connectivity options on the Omnistar L80 are satisfactory, with two HDMI 2.0 ports, two USB 2.0 ports, one USB-C 2.0 port, a 3.5mm audio jack, Ethernet, and DC IN. The inclusion of 802.11 WLAN (2.4 and 5 GHz) and Bluetooth 5.0 provides wireless connectivity options for seamless device integration. However, the absence of newer connection standards such as HDMI 2.1 may limit the device’s compatibility with the latest gaming consoles and media devices.

Audio Quality and Speaker Performance:

The Omnistar L80 features built-in stereo speakers with a total power output of 30 watts (2x 15 watts). While the speaker setup is commendable for a projector, the audio quality may not meet the expectations of audiophiles. The sound lacks depth and richness, and at higher volumes, it may distort and lose clarity. For a truly immersive experience, external speakers or a sound system would be a recommended addition.

Auto-Focus and Auto-Keystone:

One notable feature of the Omnistar L80 is its auto-focus and auto-keystone correction capabilities. This simplifies the setup process, ensuring that the image is sharp and properly aligned. The automatic adjustments work reasonably well, saving users the hassle of manual fine-tuning.


The Casiris Tech Omnistar L80 projector offers a compact design, Full HD resolution, and convenient features such as auto-focus and auto-keystone correction. However, it falls short in various areas, such as display brightness, performance capabilities, and audio quality. While it may suffice for casual home entertainment, it struggles to deliver a truly immersive and high-quality viewing experience that one would expect from a 1080p projector in this price range.

If you’re in the market for a projector that offers better display brightness, performance, and audio fidelity, it may be worth exploring other options available at a similar price point. The Omnistar L80, while functional, fails to distinguish itself from competitors in the crowded projector market, ultimately stumbling across the finish line.
