I've been using it since about February, still using it. It's running on my old M1 MBP. I have a lot of automations on OpenClaw, things like "Every week summarize this data and send me a message about it" or "check when a new version of an NPM package comes out and submit a PR to update it."

It's quite expensive from a value per token perspective. It's quite cheap from a "send one message from my phone and it does something probably productive" perspective. No major security breaches yet.
