This is a rubbish product, not worthy of Amazon. The description is misleading: it does not have 15X magnification, more like 2X, the frame is cheap plastic, the handle is plastic too and not rosewood as described, the 60mm diameter refers to the outside of the frame, not the glass.
The first time it was used the glass fell out of the frame and smashed on the floor.
I bought this, not because of the low price but because it was the only one I could find that offered 15X magnification and this turned out to be a false claim.
Buying this item has been a total waste of time. (Wifey said it's the kind of thing you would find in a Christmas cracker!)
