I had the PM size. My regret is for a totally ridiculous reason, but this is a judgment-free zone, I hope, lol ... I didn't like how it hung on my shoulder. It is hobo-style bag and I had to like fold one flap over the other or push it down. It looked messy. No clean lines. Then when I wanted in it, I couldn't just reach in. I had to "open" it up, then fold/close it back. And I am a lawyer, so I'm constantly pulling out my phone. I'd also just switched from a Totally, which had tons of easy access pockets - so that probably impacted my impatience with the Delightful. The strap was a great size, as was the inside of the bag. But having to fold it closed annoyed me a lot. I also didn't like that when I sat it down somewhere it was wide, wide, wide open like a '0' shape. I work with very honest, trustworthy people (I know, I know, lawyers are neither of those qualities, lol!) so I didn't care that it would sit open and someone could reach into it or something. I just didn't like how it was so wide open and you could see everything in it. I also found it annoying trying to slide my purse organizer in/out.
