Extremely satisfied. It was a data crawling request with many complex conditions, but they understood the requirements accurately and kindly from the first consultation. The data was delivered in a clean, organized format and was highly usable.
They handled the requested data crawling accurately and quickly. The data was cleanly organized and ready to use right away. For difficult, complex crawling — this is the expert. I will definitely come back.
It got complicated midway and took a bit longer, but I am satisfied! I want to entrust other work too!
They quickly produced exactly the information I wanted — perfectly usable for marketing. Thank you.
