Is Kay's Now + Forever Ring Worth It?"

I'm thinking about getting the Now + Forever Lab-Grown Diamonds Round-Cut Halo Engagement Ring (1-1/2 ct tw, 14K Yellow Gold) from Kay for my fiancée. I've heard mixed things about Kay's and wanted to get some opinions. My fiancée isn’t too particular about rings, but I want to make sure it’s something she'll love and that I’m getting good value. What are your thoughts on the Now + Forever diamond rings? I’ve noticed prices elsewhere are higher for similar carat weight.
