The product is very well made and does all as advertised. My workspace does not allow the light base to be attached directly across from my chair.  I have to mount it to my left side, 90 degrees from the seated direction I face.  The magnifying head cannot adjust from this position to allow the rectangular shape of the lens to align so that the longer side of the lens faces left to right.  Think of printing a page and you cannot set the printer to print "landscape" it can only print in "portrait".  To get this position the base must be mounted directly in front of your chair. The ability to adjust lens to accommodate any mounting position would be a great improvement for the product.  Again, excellent quality and price, but could be even better in my opinion.
