Super Compact Sentrym L1 Mini Projector – Built-in Android 9 OS

Sentryum L1 Mini 3D Projector Review


We have seen all sorts of projectors in the past, but today this project called the Sentrym L1 is one of the first mini portable projectors to offer so many features. It’s a projector with an Android 9 operating system with trackpad controls on its surface, and has features such as auto keystone correction and the Bluetooth synchronization with Bluetooth speakers. Now the projector does not have very powerful lumens like what we have from medium to full size projectors but it does produce a decent picture given it’s very small form factor.


Some might argue that the price point for this projector is too much given its maximum brightness and lumens and they could have given a lot more in that aspect. From and enthusiast standpoint I am quite intrigued with this device and the concept of having an all-inclusive projector/Android operating system that is rooted and allows you to install any app you want including streaming apps. Just keep in mind the operating system is not fully Google certified so premium streaming services will only play a standard quality.
