The mouse was balanced in the hand regardless of grip type, no "heavy butt" problems here. You can still see the charge light through the front and the alignment is perfect for the charger. I have used helmet straps for years and never had an issue. Superb ! (an Amazon swoosh logo would be cute). They have decent base and good clarity. Its like having an assistant who never complains when you ask "hold my bike while I spray it". In the Backbeat app you can assign when switching to awareness mode the music would pause (which is a fantastic feature). Vionic does a poor job of padding the upper portion of their shoes and this is no exception. This is exactly what I was looking for, its very comfortable and it comforms to your body shape.
