Detailed Answer
Yes (in harsh environments). Protective case benefits: 1. Drop protection (impact cushioning); 2. Dust and oil protection (work environments); 3. Anti-accidental-touch (some designs); 4. Mounting (strap points). Lider/Xingjia offer original protective cases. Indoor clean workshops may not need one; outdoor/metallurgy/shipyard sites are recommended to use one. The case must have openings (keys/indicators) — choose the original matched model.
