I certainly never thought about counting my searches. I don't have a feeling at all if 50 is a lot or not.
What I also don't understand is: so how does the counter work? If I register, I can search 100 times and then it's done? Do I move into the 5$ tier to continue and have "Enough searches to get you going", whatever that means? Because certainly it's not "Unlimited Kagi Search" since you have to pay 10$ for that.
The business model is what made me turn away right now. I don't like those kind of "funny things" around money I have to spend.
