Looks good. Installs easily. There really isn't any deep wisdom I can share about air gaps. So let me write a few words about the box. Mine came in the anonymous white box discussed in other comments. Same white box as other Delta accessories I've ordered. I read these comments prior to ordering but noticed that a Delta representative responded when there was an issue with the product. I felt comfortable when ordering. And was pleased that the metal cover matched my other Delta parts exactly.
