La bolsa no se movió durante todo el viaje de 1,400 km que hicimos y soportó las maletas muy bien. I?ve used them for at least 3 hours every day for about a week since purchasing them, so with that in mind, here we go! I wanted a small speaker that I could easily transport and that would be rugged enough to live in a "shop environment". Good looking, and bonus: $12. Best ?ANYTHING? finder available. There is a super range of colours here, exactly what I need for my current project and I should be able to use the beads for months to come. However, when the new pair arrived, I quickly realized the new pair was inferior. He wears them to his swim classes and while playing on grass. I wouldnt recommend wearing them outside or around pool or anything. Really thick, & fits the bar well without even using the straps to secure it.
