The tool is generally good and helpful for basic regex testing. However, I found the performance slightly slow when dealing with extremely complex patterns and large input strings. Also, the documentation could be improved with more detailed examples. It's a decent tool but has room for improvement in terms of speed and comprehensive documentation.
