Never having had a a projector before I was intrigued to find out how easy this to use so here is my review! There are a number of ways to connect including via wireless and Bluetooth. It also comes with a HDMI cable and you can use a vga cable. Using wireless on my phone was handy but don't rule out using your computer. I was able to play a movie from my laptop, using the projector screen whilst looking at my emails on my laptop. Both are useful.
When you are setting up, you might find some difficulties, not because it is hard to use but because there are a number of different settings. There is a really helpful Mini Projector FAQ's and they are definitely worth reading until your get used to the projector.
It also comes with a stand - this for me was one of the best features. It allows you to change the angle via the legs and also via gimble on the stand. I even found, as can be seen from the last photo, that it works on a soft surface such as bed. So if you want to project it from your bed and watch you movie you can! The remote control also helps for watching a movie in bed.
