i run a lot and i don’t recommend these for running but fine for casual. i have thrown in a few good scores and it's just a question of trying to put four of them together. i was seeing others videos and thinking what i can suggest to the icy veins. spider bought some water and lots of snacks. longer trips add at least an hour every hundred miles to the travel time while i stop to refill the batteries. the seller responds he would burn the place down before they would give it away at that price.
