It's proved handy for me already, actually.

Do you find it accurate for you most of the time?

I can't say if its more accurate then it was before yet.

Google Translate is still definitely not a threat to human translation:

"In order to gain the upper hand, we would have to go all out in the next round," translates to, "順序では、優位を得るために、我々は次のラウンドで、すべての外出しなければならない。" Which means, "Sequentially, to gain superiority, in the next round, we'll have to put everything outside." Unless you're translating for some sort of moving-based reality TV show, I don't see the result as being remarkably accurate.
