Strange robot corrects, some mistakes are overseen – eAngel Human Proofreading Review

I submitted 2 similar texts, 200 words. I received an answer in 1 minute. No way a real person could read and correct it within that timeframe. Interestingly, one text returned 2 different corrections. Some unnecessary (i.e. wrong) corrections were proposed, some optional changes were made in the case when both phrases were correct. Some mistakes were corrected in one result and were not corrected in another one. As you might know, they price you based on the number of corrections they make. From what I saw in my case, they do make extra amendments even if those changes weren’t necessary. Only facts. It’s up to you to decide.
