I bought this software hoping to streamline my WhatsApp marketing. It worked okay for smaller tasks, sending messages to a few contacts at a time. However, when I tried to use it for a larger campaign, it became quite slow and prone to errors. The interface is user-friendly enough, but the lack of robust error handling and speed for bulk operations is a major drawback. It needs significant improvement in its ability to handle large datasets efficiently to be truly useful for professionals. For small-scale use, it's acceptable, but I wouldn't recommend it for anyone needing to manage hundreds or thousands of contacts. I'd suggest the developers focus on improving performance and error handling for bulk operations before considering it a complete solution.
