It's good. However, at times it tends to overcorrect using unnecessary hyphens between verbs and prepositions when it's understood, along with too many commas unneeded. The 'free service' may be a little bit robotic compared to the days when I learnt grammar at school and wrote essays or compositions in primary school back in the 1950s and 60s. I am a writer in English and Spanish. I hope you see my comments as constructive. Thank you from Stephen
