Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on the automation, and it is genuinely easy to set up caught me off guard. still, I'd recommend giving it a real trial.

Use it every day

Honestly didn't expect to like it this much. The automation is exactly what I needed, and the value for money is strong. I do wish pricing gets steep at scale, but I reach for it almost every day now and it just clicks.

Years in this space

I've evaluated a lot of these over the years. What stands out here is the API — handled better than most — and it saves real time. Worth the time if this is your use case.

Use it every day

Honestly didn't expect to like it this much. The integrations is exactly what I needed, and the value for money is strong. I do wish the mobile experience lags, but I reach for it almost every day now and it just clicks.
