A couple months ago, they upgraded the Ring app and it's much faster now. Not fast, mind you, but in the neighborhood of acceptable (for me anyway). I'm happy enough with it, but I suppose it depends on your use case. I pretty much use it just to monitor comings and goings and package deliveries. I rarely answer a ring through the app. I don't have any issues with not being able to connect. I did a couple years ago, but they've resolved all of my issues with software updates.
I like the idea that the video isn't stored on the device itself. If someone steals or destroys the device, I still have the video in the cloud. I don't find the subscription fee to be onerous. At $39.99/year, it's cheaper than a single meal out with my family. If it was too high, I would figure out a way to roll my own to web storage that I'm already paying for, but at that price, I can't be bothered.
So I'm a satisfied customer.
