Google is getting VERY good at catching spun content so you'd better be talented at manual spins. If they DO catch you, of course they'll spank you... and hard. So anything you use spun content on is inherently AT RISK. Worse yet... Google gets better at finding spun/poor content every year. So in the longrun you're screwed. I'd weight your other options and see if you couldn't find a cheaper source for manually hand written content.
Rewriting your article by hand is the classic approach that is slowly dissolving, however, many people still prefer so. Write manually and then rephrasing to ensure the finest quality is the safest way but it can often hours, days or weeks to finish a writing task that can otherwise take only a little time. And that’s why there also exist people who like to save the trouble and their time, so they look for an article rewriter or article spinner to do the job.
Nobody is immune to spelling and grammatical errors, not even me. It doesn't matter how many times you proofread your content, sometimes an error slips through the cracks. But, too many errors in your writing are bad for article writing services business and can also hurt your reputation over time. If customers are annoyed by poor grammar on social media or on a small blog post, just think about how they will feel if they receive an email or eBook laced with these errors.
