Hello My-STE-Buddy,
I'm very happy with My-STE-Buddy. I was skeptical at first and opted for a monthly subscription. I quickly discovered it saved me a huge amount of time. You say 2.5 hours per 600 words. I haven't been able to achieve that yet, but I still save a lot of time with large documents. I'm going for the annual subscription.
Sincerely,
Wáng Lì
MY STE BUDDY
