Review on Amplifier Bluetooth Adjustable Compatible Smartphones by Warren Hess

So the magnifier works as advertised and the speaker connects via Bluetooth and works. However, the picture on Revain and the description of the functions are missing. The biggest problem is that the description says it has "built-in 1*18650 battery, you can use the cell phone projector to charge your phone while watching movies." Although it has a battery (only for Bluetooth speaker/microphone) and you can connect your phone to the back of the projector. However, you cannot charge your phone with a battery. The whole device needs to be plugged into the wall as if you charge the device to charge the phone when plugged into the back of the device. This is stated in the instructions supplied with the device. From the picture here on Revain it looks like there are two speakers on the front. no There's only one speaker on the left side, and there's an artificial notch on the right side to make it appear like there's a speaker. Instead there is a hole for the microphone. The last picture of the Revain (and the box it came in) shows the adjustable arm (looped) with a clip. Mine didn't come with that hand. The part that attaches the arm to the bottom of the magnifier was in the box, but not the arm and clip.
