**Editorial Review** The USB Engraving Pen, accompanied by a comprehensive selection of 47 bits and 10 metal business card blanks, has become a topic of interest among DIY enthusiasts and crafters. Many users have found its utility in small and intricate tasks, such as cleaning up 3D prints, buffing, sanding, and polishing small objects. The tool's lightweight and cordless design adds to its appeal, making it a convenient addition to any craft room. Despite its versatility, the engraving pen is accompanied by a few notable drawbacks. Users have reported a lack of included instructions, which may make it challenging for newcomers to maximize its capabilities. While the engraver performs well for fine detail work on materials like metal and tin, it falls short when it comes to more robust tasks, such as carving wood. Additionally, the battery life has been a concern; many users noted that it drains quickly and requires frequent recharging, which may interrupt longer projects. Some users have also indicated issues with the durability of the engraving bits, which tend to wear down with continuous use, necessitating replacements. The fitting of the bits into the pen can require some force, which may not provide the smooth experience that users might expect from a tool designed for precision. Overall, the USB Engraving Pen offers a solid tool for detailed craftwork, though it may not meet the demands of all users, particularly those looking for a more powerful engraving or carving tool. It is advisable for potential buyers to weigh the tool's strengths and limitations to ensure it aligns with their specific needs. **
