A perfect name for the Hausbell Waist Trimmer. It is adjustable and the wearer does sweat when wearing the belt. I can't exercise due to extreme back pain. So I wear the Waist Trimmer Sweat Belt Waist Trimmer at home or if I'm going out to a doctor's appointment. It is a good back support for my type of lower back pain. I deduce that the belt will help trim my waistline if I use it as often as I can tolerate wearing it. Thus far I have not noticed any weight loss yet. Then again my weight lost journey is a little molasse slow going, because I cannot accelerate my exercise goal due to other health issues. I do appreciate the Seller for offering this product for me as a customer to try. Thank you!
