Stackpath CDN experience

Does anybody have any experience with the Stackpath CDN ( https://www.stackpath.com )? They have recently gotten a lot of traction by acquiring not only MaxCDN (in the summer of 2016), but also Highwinds last month. This move easily makes them one of the top competitors in the CDN space, and the merge went through pretty much unnoticed on Hacker News.

This makes me wonder whether somebody here has any experience with Stackpath CDN or can share some information regarding their service quality. Are they really as good as their pricing (0.02$ - 0.06$ per GB) promises?
