Maybe it's because I'm a fast reader, but the jury duty studies are great $$/hour for me. I usually finish 15-20 minutes before their estimated time. You just gotta pay attention to their comprehension checks and as you said, if there's any tech issues, you just gotta return the study/give up. Thankfully it's only happened to me once and I only spent about 5 minutes on it before I ran into the problem. But overall, my experience with them has been really good on Connect. They easily make up 70%+ of my income on there.
