Possible disadvantages of Data Miner

• Limited Free Tier
  The free version of Data Miner is limited in terms of the number of rows and pages that can be scraped, which may not be sufficient for more extensive data collection needs.
• Learning Curve
  While the interface is user-friendly, there can still be a learning curve for users unfamiliar with web scraping concepts and the tool itself.
• Browser Dependence
  As Data Miner is a browser extension, its functionality is limited to the browser environment, which might not be ideal for more complex or large-scale web scraping tasks.
• Potential Website Restrictions
  Some websites actively prevent scraping activities, which could limit the effectiveness of Data Miner on certain web pages.
• Subscription Cost
  Advanced features and higher usage requirements necessitate a subscription plan, which may be costly for individual users or small businesses.
