Using this kit is a breeze. First, gather your tools - just a screwdriver. Take the laser - cut lens holder and place your convex lens (if it has a lip - edge) into it. Then, use the included 8 M2.5 5mm screws and 4 M2.5 6mm F - F hex standoffs to attach the holder to your HalloWing. It should take less than five minutes. Please note that this kit only works with the HalloWing, not other display breakouts. As for maintenance, keep it clean and dry. If it gets dirty, you can gently wipe it with a soft, dry cloth. Don't use any harsh chemicals as they might damage the acrylic lens holder.
