They claim this belt is adjustable for size 28" to 44" inches. This is completly wrong. 28" to 44" is a 16 inch span. The black band insert on the back of the belt that the buckle requires to grip to function is only 8.5 inches long, thus making it physically impossible to have a 16 inch adjustment span. My waist is 38-40" and where the buckle rests the band in back has already stopped. You cant trim it because you would be cutting the part that already has the black band and you would just be removing the functional part and exposing more of the belt that the buckle can not attach to. The black insert needs to extend another 8 inches deeper into belt to work.
