The tiers have changed over time. Originally $10 was 700, not its 1000.
I use search A LOT for work. I also have it on my phones etc because I dont feel like swapping engines all that often.
I find it giving me more acurate results quicker, without ads.
The only other subscription services I use are mostly Netflix for kids and family. I avoid them at most costs. But this one allows me to do my job a bit more efficiently and its privacy focused.
