Review on Bluetooth 1920X1080P WiMiUS S4 Compatible by Bret Wong

I have purchased, returned and redeemed 3 units so far. This device is cheaply made but mostly works as advertised. The lens cap doesn't always stay in place. The picture quality is pretty good. One of my 3 embroidery edges was fuzzy which was annoying. The Bluetooth feature is darn cute and should be a standard feature these days, but unfortunately it isn't. I sent one back as the function was not connected. The volume is not great, but the quality is okay. The inability to focus the image size without moving the projector is inconvenient. This makes it impossible to place the projector where you want it. It all depends on the specific distance to the screen. Why isn't there 4D keystone correction? It seems like an inexpensive option to add a very useful feature. They are usually missing in this projector price range. Looks beautiful. But the dials are very crudely made and work pretty poorly. But polishing these inexpensive features will make this projector that much better. So it's ideal for situations where you don't have to rely on such limited restrictions. Overall a great product for the price! This is not a quality product so be prepared to discard if you expect it to be added. It works, the pictures are good. And you will make your movie nights out of it. But you won't impress your video snobs.
