I've had my BAM case for a decade, liking the lightweight solid protection, and putting up with the scuffs, buffing them out with car polish cleaner. A recent tumble with case in hand convinced me to look for extra protection (although 260 year old viola was unscathed even though I was not). This cover does offer some peace of mind; however it is by no means "no weight" as the manufacturer suggests: I reckon 1 to 1.5 lb. additional. The case cover is somewhat loose fitting, so that it does not cling to the case, especially since the case itself is so slick. All in all, this is a practical solution for me.
