If I am still riding after an hour, I usually have to reinsert the left one, but that probably has more to do with the shape of my ears than this product. The fasteners consist of protruding machine bolts to which nuts are to be attached. I also like that I just sit the speaker on the cradle and not have to worry about aligning. I did want the sup case but it seemed out of stock. What I knocked a points off for is the workmanship. The toe box is nice and wide and flexes well right out of the box. And best of all it is one of the less expensive wireless mouses out there. Still, overall, this is well made and designed. I received several compliments on the dress. These attachment straps are located low towards the base of the bag and so there don’t “hold the bag down” on to the roof of the vehicle.
