Another Kagi user for a year or two. I've honestly never had a single negative experience. Since using Kagi, I've only had to use google a couple of very desperate times. I don't notice the subscription fee because I get excellent value from it.
Kagi simply does what you ask and stays out of the way. Because you pay them, they don't need to monetize every pixel on the screen. No tracking or data mining. It's just software that does what it says it does and does what you tell it.
It's tragic that "thing that does one thing well and doesn't spy on you" is a scary and alien concept these days.
