Bright and loud for its size.
Nice bright image from such a compact unit, the sound is surprisingly decent too. Minimal laser speckle and barely noticeable rainbow artefacts. Limited colour settings but it's fairly good out of the box. The autofocus is more miss than hit but it has a manual option and you can turn off autofocus in settings. It also has a sleep timer which is handy. Runs a firestick with no issues and has CEC so the projectors remote controls the firestick. Occasionally doesn't recognise external thumb drive. Good enough for the price.

Osoeri 4k
The Osoeri OS-RA02 projector is excellent! The picture quality is great with vivid, sharp colors, and it offers many hidden settings and advanced color adjustments that let you fine-tune the image perfectly. Auto focus works quickly, the menu is easy to use, and the number of features really surprised me. I’m very satisfied with this purchase and highly recommend it!

Very impressive!
After having cheaper models of projectors from other brands, this projector has absolutely exceeded my expectations! It arrives with a padded and compact storage bag, charging cable, remote control and the projector itself, which is compact and easy to store and travel with. The projector is easy to set up and use, with clear and useful instructions provided for use. The projector can be connected to the WiFi, used via a HDMI cable or USB, connected via screen share and also has capabilities for saving media files as well as connecting to a range of apps. It can also be used to charge other devices or as a speaker so extremely versatile. Connecting to another device is very easy and quick to do. The quality of the screen really is impressive. It is very sharp and clear, with automatic focus as well as manual focus. The projector is controlled either via the buttons on the top of the unit or via remote control. The buttons on top are touch screen and easy to use. The unit is charged via cable and can hold its charge which makes it completely portable and can be used anywhere. The unit has its own speakers and plays sound from the unit. This is crisp and clear, which functionality to adjust the volume and tone as needed. Overall a solid recommendation for a high quality and extremely impressive projector.

Compact and Feature-Rich Mini Projector with Room for Improvement
This mini projector is a great portable option for those seeking big-screen entertainment on the go. Its native 1080p resolution and 4K content support deliver a decent viewing experience, although not all 4K files play smoothly. The built-in Android 9 operating system allows for app installation and streaming, but the user interface could benefit from optimization for a smoother experience. The image quality is generally good, with fast autofocus, but the lack of zoom control can be limiting. I encountered occasional issues with the Wi-Fi connection, which sometimes failed to turn on, indicating potential software bugs that hopefully can be addressed in future firmware updates. Connectivity options are somewhat limited, with only one USB Type-A port, an HDMI port, and a USB-C port for power. The absence of an Ethernet port, audio jack, or AV port might be a drawback for some users. Despite these limitations, the projector's portability, built-in battery, and decent sound quality make it a compelling option. The price point, however, could be more competitive to make it a truly attractive choice. If you're looking for a compact and portable projector with smart features and are willing to overlook some minor software quirks and connectivity limitations, this mini projector is worth considering.

I am more than satisfied and surprised by a fantastic projector with a good picture and great sound and can also install different apps. I am completely surprised by this fantastic projector. We will have it in the motorhome with a picture of 50 inches, very good quality and sharpness, image sharpness has autofocus and 30,000 hours. and the best of all that you can see for at least 3 hours with the projector battery life. Do not hesitate to recommend a super good projector for the money. and is really 4K quality. More than satisfied… 🇸🇪
