LARGE 4" LED WIFI NETWORK SYNCHRONIZED CLOCK

I am very disappointed with this product. I am on the verge of returning it! There are no in-box instuctions which is tolerable. However, to sync the clock with WIFI, you need an Android or PC computer, which is NOT clear prior to purchase. Why is that? Half the world uses MAC. So I bought a PC tablet to configure it to my WIFI. The illustrations and instructions in the online owners manual are not the same as what appears in the WIFI interface on a PC tablet. My last resort is to hire an IT soecialist to get it to join my WIFI so that the time is synced for my daily live radio program. Im usually patient and very competent with technoligy, but this product lacks a stable customer interface. Sorry folks. You can do much better.
