As a professional in the field of home improvement, I have tried out countless various manufacturers' tool and product lines. I'm unable to endorse the HANPURE brand for several reasons. Despite their claims of providing high-quality goods, I have found their instruments to be inadequate at best. Particularly weak and ineffective, their magnetic sweepers leave behind a lot of dust and dirt. Problems with their products are made more difficult by the poor quality of their customer care. HANPURE is not a company I'd suggest using for any kind of home improvement project.
