Two things persuaded me to purchase this site. One was its size and shape; the second its apparent sturdiness and slip resistant build. I wanted a go-to magnifier that could be left out and resorted to at will without fear of damage yet would largely fulfil needs for magnification. While not the largest viewing area this magnifier does the job. I also like the composition of its exterior which supports my original desire to have something handy that would withstand the rigors of continual use. The handle is long and has a non-slip exterior which supports that purpose. This is good magnifier for everyday use will withstand daily wear and tear.
