On the safety front, it excels with IP64 protection against harsh conditions and 10 different safety features, including spark-proof and temperature protections, ensuring safe usage. Some users might find the price point higher compared to basic models, and its advanced features might be more than what a casual user needs. Additionally, while the compact size is generally an advantage, it could be seen as less rugged and durable than bulkier models designed for heavy-duty use.
