As someone who has always wanted a projector but never actually got to use one before, I was really impressed with this ERISAN portable projector. Right away I was surprised by how small the device was, and how light it was. Setting it up was very easy, as it just required I plug it into a power source and turn it on. When using it in a dark room, I was able to project the screen onto my living room wall and adjust the focus to be incredibly sharp, and I was able to repeat the process with my ceiling easily. Obviously having a screen would be beneficial for a long term setup, but if you have a blank wall, it's enough!

The projector supports a TON of options for getting your content onto it. I personally used a USB stick to play movies and create a picture slideshow, but it also supports connecting to a PC via HDMI, inserting an SD card, attaching a dongle like the Chromecast, and an AV port. You can also use the HDMI port to connect it to a video game console like the Xbox One or PS4 and play video games on a huge projected screen.

The projector does come with a built-in speaker, but it's not very good and even the product listing suggests attaching external speakers. Any audio jack speakers will do, such as those you use with a computer. When using it for a photograph slideshow, I found that the colour levels were a bit oversaturated, despite the fact that movies I watched seemed to be fine. I couldn't find any setting that would allow me to fix that, or to customize the slideshow settings, which was another nitpick of mine. However, at this price range, that's basically to be expected.

After experimenting with this projector, I have to say that the possibilities are pretty huge. It works on walls of various sizes and displays a very sharp image, but you can also set it up with a large screen for a backyard movie, or hook it up to your gaming console and enjoy playing games on a massive screen. Whatever you might use it for, this projector is small, extremely easy to use, and does a great job.
