Im sorry I waited for so long to get these. Cumple con la funcion requerida por el precio que pagas es bueno, solo que deverian de modificar un poco el resorte donde se sujeta la bicicleta, se traba un poco para ajustar, pero funciona bien They stay connected pretty well, occasionally they?ll drop if you haven?t been playing anything for a while. They have great sound quality, especially if youre looking for something with bass. This strap is the best solution Ive found. Ah well. It is one of the very few screens on this unit that isn?t as clear as it should be. No surprises there. This is a perfect organizer for all of my spices! Below is a little more detail:Physical: No physical damage at all.
