Excellent

Involvement:General (knows how to use it) - Ownership:1 day to 1 week

Metal and glass, not cheap plastic thing.
I use it for offset printing inspection, and it works perfectly.
The carrying pouch fits very well and protects the magnifier.
Can be used with the base closed, like a hand loupe.

None at all, but the inside area is 1 square inch, (1inch x 1inch), the 1.5in in the description is the outside size. For me, this is a Pro, but could be a Con if you are expecting for 1.5in area

Don't know how much it magnifies, but probably it's for inspecting offset printing dots indeed, and it does this job very well.

If you want a good 1 square inch area magnifier, this is exactly what you want.
