This lens is powerfull, clear, sharp, almost distortion free. Great for PCB inspection. Follow mfr's manual if new to 10x lens. Can see almost 1" of a PCB in complete 10x mag with little distortion and no color issues. Reduces eye strain, easy to wipe clean.
I use it daily with great results. Case is plastic, but strong. All glass elements. Anti-rflective coatings as good or better than my DSLR camera! Was on backorder for a while (3 weeks??), but worth the wait! Any problems I ran into were from my OWN eyes not being as good as the lens. Would recomend to others. Would reccomend the optional case to protect the lense from grit. I also use this lense in my rock-hunting hobby, electronics hobby. This lense is a serious addition to my tool box. Hardest part was training my eyes to work with it properly.
Pros: Excelent Optical quality, Light weight, bright image
Cons: Learning to use
