The current version just covers the LCD display, and you tend to see a rainbow effect around the edges of the cover (alternates between red, green, blue). I wore these on a 75 mile backpacking trip through sand, gravel, and forest. 6feet! It was nicely packaged. But remember, this is not an expensive weightlifting bar, and the flex/whip in this bar is about what I would expect from a utility bar in this price range. The battery life has been plenty good for me. This noise started to appear even when the switch was not touched, leading me to try to touch it, change its position a bit, so that it stopped. This case comes with a sturdy karabiner type clip which is useful if you wanted to clip it to your trousers. They seem very durable and well made. I couldnt be more pleased!
