To explain my less than stellar grade: As I am enamored with the concept, and after delivery, quality, of this belt design, I can not at this time offer a true review. After many frustrating attempts to use the belt, I have come to believe I purchased a strap that is too small for popper operation. (Although I did adhere to the sizing recommendations offered, watched the instructional video, I as an individual that is larger than the average bear, I would advise buying a size, possibly better yet, two sizes, larger than your pant size). I will keep my positive nature in regards to my newer eating, exercise habits, and weight loss so, therefore, I will keep the smaller strap and order a larger replacement strap. Fingers crossed.
