I left this feedback directly to L33T a week ago, but I haven't heard back since I sent him this. I'm just dropping this here now as it might serve to better pace others' expectations of the service.
I should preface: After reading the countless reviews singing praises-on-high, I went into this with great expectations and was under the impression that this would be among the best writing services I could choose on BHW.
I purchased 5x 1000-word articles under the "SERPEDIA Premium Package" @ $3/100 words to help flush out content on my viral content site for Adsense approval.
The work I received was ok.
All content passed Copyscape, which was the primary goal. But I was hoping to see a lot more substance for the price I paid. I noticed some grammar and spelling issues that were mostly trivial, but certainly allude to the possibility of spinning. Fair amount of useless repetition in phrasing and word usage. And many parts read as if they're written by someone non-native to English speaking. After combing through these in Grammerly, I was able to polish them up for publishing. But it took more effort than I wanted to deal with or had time for.
I understand that $3/100 word pricepoints can sometimes be prohibitive to the quality of output, but that's what I thought I was paying for here.
Let me be clear - this is not a bad service if you're looking for low-level filler content that passes Copyscape. But with such glowing reviews, I think my expectations were placed a bit too high.
Unless there was a mistake and I was sent the wrong deliverables from L33T, I'm currently seeing the same level of content quality output from mainstream services like TextBrokers and iWriter at a substantially lower rate.
