### ⭐⭐⭐⭐ Works great, short cable
*by R***B on August 14, 2025*

This product performed exactly as intended, delivering reliable results and meeting expectations for its intended use. The only drawback was the noticeably short cable, which limited placement and flexibility during use. Otherwise, it’s a solid and effective choice for the purpose it was designed for.
