Hey everyone.

I'm considering the XJ-HOME E21 Portable 1080P Projector and would love your insights on a few key areas. First off, how does the picture quality hold up in different lighting conditions? The 15000:1 contrast ratio sounds promising, but I'd like to know if it truly delivers vibrant colors and clarity, especially outdoors.

Next, I'm curious about the sound quality. With Bluetooth 5.2 connectivity, does it pair well with external speakers or headphones? Can it fill a room adequately on its own, or is an external sound system a must?

Additionally, what are your thoughts on the overall system? The Android 9.0 integration sounds neat, but are there any limitations or downsides you've encountered with app compatibility or performance?

Lastly, I’m wondering if there are any potential downsides that I should be aware of before making a purchase—like reliability issues, setup complexity, or anything else that might affect my experience.

Thanks in advance for your feedback!
