Really tempted to go for this as well. Only wish I could access flat rate Claude through VS Code Cline (or an extension like it) as well - that would be the complete package. $100 / month + ~$$ / day in API credits is gonna get pricey.
I have been using Claude Code a lot since the Max plan change and I've never hit the limits myself.
Edit:
Found the answer to my own questions
> Send approximately 50-200 prompts with Claude Code every 5 hours[1]
Damn. That's a really good deal
