First let me say I love Tugmutt and their products. I keep extra bands and other parts on hand to promote continual use for my Mals. The two replacement velcro carabiners that I received were smaller than the original, and one replacement carabiner by itself would not hold more than a minute or two of use. After a bit of thought, I applied one, and then applied the second wrapped just a touch bigger around the outside of the first. With tandem application they are now holding, but it appears the strength and/or quality has diminished, as the original lasted well over a year-and-a-half. At this rate I'm paying double for a working replacement. Heads up for the QC department. =0)
