## Questions & Answers

**Q: Why does the controller work fine, but I can't swipe the controller mouse like a regular computer mouse?**

**Q: Can I install Netflix, Disney+, and HBO apps on the projector for watching?**
A: Yes, you can find the apps from "Get Started" on the home page menu. If you cannot play the app properly, you may install the wrong version of the app which is unsupported by J4a. Recommend installing the right version of the apps from "Get Started".

## Customer Reviews

### ⭐⭐⭐⭐⭐ Pretty great!
*by D***L on 16 April 2023*

It's compact, lightweight, and comes with a built-in battery. The image quality is good. Plus, the built-in Android operating system means you can access all your favorite streaming services and apps without having to connect to an external device. All in all, I'd recommend it to anyone who wants a portable projector for their outdoor adventures.

### ⭐⭐⭐⭐ Almost perfect
*by V***A on 25 June 2024*

It seems that I finally found the ideal pico projector, after some searching. Everything is rather ok, image, its brightness, etc. The picture is pleasant, not hard to view, unlike in many pico projectors, including more expensive, like Asus or even Kodak. The rate of changing is rather high. I used the pro mode of the camera to notice it. Even at the shutter speed 250 or 100 it's already almost invisible! Note: even in more expensive models it's visible at the shutter speed! Thus it's really easy and pleasant to view. However, there's still issues. Weak sound, and I couldn't find how to switch on it, using only the remote. Also I wasn't able to find the screen size change settings, but it was mentioned on an internet instruction -?! So where is it hidden?? In whole, it seems that the pico projectors in the price category, under £200-150, are still raw products and in need of certain improvements. Not mentioning the price tag reducing.. Even the regular lcd mini projectors , even in the price of 45-100 have all the features already, for example.

### ⭐ Not worth it
*by V***G on 1 December 2022*

It doesn't worth it for that price, you can find something much better for that price. It's really slow and apps do not work really good.
