I bought a three pack bundle of three different buckles. The material and finish of the belts and buckles were outstanding. The extreme low weight and profile of the belts were just what I wanted. When used in an office and home environment the buckles performed very well and remained snug and comfortable. When worn in a work environment with constant twisting, turning and bending the buckles did not stay tight and had to be constantly tightened especially when anything was attached or hanging on the belt such as a knife, tool or sidearm. I did watch the short videos on your website on how to use and properly wear the belts.
