AC Question

is it compatible with my phone?

I have an HTC desire 816. I'm interested in the smartband talk SWR30. I emailed the maker and the reply was a pdf and saying to check there. Well, the pdf was extremely useless. How can (and y do they all do it) a company make a Product and yet are never helpful in answering ?s. They're always giving useless replies. So does anyone know if my phone is compatible with this product? Thanks
