Using this Pibow Royale Touchscreen Frame is a breeze. First, take out the frame and the provided bolt pack. Since no tools are required, you can directly screw the 3 layers of the frame onto the back of your 7' Raspberry Pi Touchscreen using the bolts. Once that's done, use the 2 legs to prop up the screen at an ideal viewing angle. The touchscreen won't be blocked, and you can easily access all the ports of the Raspberry Pi. As for maintenance, just use a soft, dry cloth to wipe the frame regularly to keep it clean. Remember, this frame doesn't come with the screen and the Raspberry Pi, so make sure you have those separately.
