GOOD: ---------------* 5.5 inch squares, each weighing just over 9.3 ounces.* Both Both inches and cm on the sides are very accurate according to the angle finder.* Four sets of clips are included. They can clamp boards from 7/16" to 1-9/16" thick BAD: ------------* The amazing quality of these unknown brands made me realize how overpriced woodpecker tools are . There are 5 stars for a small price.
