To quote a recent comment from the Amazon website:

This product was supposed to be blue tooth compatible but had so many bugs in the software it was impossible to make it work with my phone. Coupled with the greatest example fo customer NO SERVICE from their service operation, I think this company should be sent to the scrap heap of tech companies that make junk products.

In order to set up this keyboard, a person needed to download software from their web site. But the software was not where it was supposed to be and, when finally located, didn't work.
