Strengths Excellent quality. Clear and sharp images. Great optics. Magnification is a true 4.5x. Wide and good depth of field. Comfortable. Very lightweight for 4.5x. Large selection of frame styles and colors. Very good technical support and customer service in most locales.
Weaknesses One evaluator needed to take them to a local optician for proper fitting and alignment. Getting adjusted to 4.5x can take a while if you’ve been wearing a lower power. One evaluator did not find them to be comfortable. Another evaluator never could get the local rep to provide adequate adjustments.
BOTTOM LINE Excellent optics, resolution, and lightweight along with true 4.5x magnification, but at this power (as with all high power loupes), having them adjusted perfectly is essential.
