3D Hologram Projector Fan LED Holographic Advertising Display

Hard to program and remove demo. But once you figure it out, works and looks great

Seems I may be one of the few probably “real” buyers - “Amazno” customer or whatever seems fishy. But, it works well enough. Only complaints;1) app is a bit bad - not obvious and no help. You have to use non-obvious buttons to “transfer” to do the actual “save to .bin” file to latterly copy to the mini SD.2) it is possible to plug the SD into the fan part upside down and loose it in the moulding! Luckily, the front clips off easily and it was retrievable.3) Seems it is generic and available at other places for about $150 v. $200.

Fan won't read anything but the demo pictures (bins). In fact make your own bin (or download one) and put it on the SD card with the demos and all it will play is 3D Hologram.

Awesome customer service!! I like the fan.

While this came promptly and worked, the SD card slipped between the reader and the casing of the unit and was lost forever. I consider that a huge design defect because not only did I lose the card, I lost the program, making the unit useless. Returned.
