I bought this deal with low expectations, as I use other uptime monitoring tools already integrated with MainWP.

That said, within 24 hours of setting it up, Better Uptime had already caught two very short periods of downtime (actually, scheduled maintenance on my site) that the others missed, and the entire experience, from the notification through to acknowledgement and resolution, was a clean, smooth, and clearly well-thought-out journey.

Now, if only they can get a MainWP extension built so I can replace my other centralized monitoring tool this one, and I'll be a happy man!
