What are your recent experiences using Parse.com?

A little over six months ago, a similar question was asked on Hacker News: https://news.ycombinator.com/item?id=8347310. since then, Parse has explicitly said they've been working on reliability and their infrastructure. With all that in mind, what are your recent experiences using Parse.com in production environments? The general vibe I get is that it's great for starting out, but not so great as a sustainable platform.
