Insta-parser is a product of the company Zengram, which can be noticed in the FAQ section that refers to their website. I have been familiar with this company for a long time and have used their services for promotion multiple times, so I had no concerns when using the parser. The price of the parser is quite high, especially considering the volumes, so its use is unlikely to be justified for small businesses. However, for large companies, there is an excellent unlimited plan that is reasonably priced for serious businesses. I just switched to it to avoid worrying about limits. The service is easy to use, has a modern interface, and clear settings for parsing and filtering the database. It's easy to figure out what to click on from the first try, and in case of difficulties, there is a detailed FAQ with plenty of screenshots. Account collection is accurate, and only suitable profiles make it into the database after filtering, so the parser filters out unnecessary data.
