We've carried out an A/B test because our company had two different places in the shopping mall to see which one worked better. The 3D fan beat the other group hands down, by appealing to more customers and increasing the sales volume. The image is clear and it is really awesome to have the display. You can see the power of the visual effect!
Works better than the flyers! Because the 3D image seems to be more attractive. It's more environmentally friendly, too. The only problem is to find out where is the best for the advertising.
