Great but expensive
I like it a lot - it’s like a reference book on my phone. Problem is it’s also quite a bit more expensive than a reference book because you have to keep paying for it monthly. If it were one flat fee I’d say it was worth it but being charged constantly for the same resource is not worth it. I’d recommend a book instead.
