Wow! That is a low price!!
One of the things I like best about the Optivisor is that, like this device,
it is binocular. I didn't get the loupe with mine and have never missed it
(used an Optivisor for nearly 25 years so far).
What I do to adjust the magnification for really CLOSE work when needed is
to wear my reading glasses with it. When I want a little less magnification,
I just take off my reading glasses (or slide them down where I can look over
them like I do any time). That's the second real advantage of this type of
aid - you can use it with or without supporting eyeglasses.
Where I've seen cheaper lenses go bad is when they aren't optically
correct - have distortions and imperfections in the lens itself. One test I
use is to hold the lens in front of me and rotate it while looking through
it at a straight edge. If the line bends or bows, the lens isn't good
(unless it happens to be a prescription lens ground to correct astigmatism
G).
It sounds like you got some good lenses in yours.

Fellow builders,
...I just received this Magnifier yesterday and thought
others might be interested. Total cost is $9.80 with Priority Mail shipping
and Gadgetman is a pleasure to do business with:

Although this product is made of plastic, it is a fraction of the cost of a
glass Optivisor with comparable lenses and loupe.
I have no connection with Gadgetman other than
being a very satisified customer.
