I’ve been using it for almost a year now.
It.. works well enough. I really have no complaints, tho it does have some cookies, which I could do without (I don’t care to track how many trees I’ve contributed to planting, and I’d like a no tracking option) but that’s a pretty small complaint when I clear cookies frequently anyway. If you use ghostery or some other extension that auto-rejects cookies and randomizes data for those it can’t reject, you’ll be fine.
The sponsored listings are clearly labeled, the results typically come up fine. There do seem to be more sponsored results than there used to be, though, so.. something to be aware of.
It’s not perfect but it’s a lot better than google, and they use the money for trees (I did look into that claim and it’s true as far as I can tell)
Personally, I’d go for the person. Roach phobia entirely not factoring in here.
My attic is over a detached garage. If someone can access that space somehow, and wants to live there, whatever. It’s roomy enough to be fairly comfortable, tho you can’t stand up straight, and it’s insulated with electric outlets, so I’m not suuuuper likely to find a frozen person in spring. Not great, but as long as they don’t leave a mess or whatever, meh, doesn’t harm me any beyond electrical use. I probably wouldn’t even find out about it for a long time, since I never go up there; the ladder is duct-taped where it cracked at some point, and I can’t be bothered to replace it.
Roaches, however, would not stay contained to the garage. That’s a deal-breaker.
