• Heat Durability Over Time: With frequent use, some users have noted that the stainless steel blades may require extra attention to maintain sharpness, and the heating element may wear down over time with heavy use.
   
• Complex for Beginners: While the tool offers great precision, the temperature control and blade-switching process may be intimidating for beginners, making it less approachable for first-time users.
