Thanks, Dick. Couldn't have said it better myself. My Dinotte sits unused on the shelf because to use it you have to mount the light, mount the battery pack and hope the batteries don't shake loose while you ride. Then charging is an ordeal. You have to remove the auxiliary velcro strap that keeps the batteries from coming out of the holder. Put the (4) batteries in the charger, then put them back in the holder, put the holder in it's sack, put a strap around the holder, connect the holder, mount the holder, etc., etc.
My Shiningbeam flashlight snaps in and out of it's holder with one hand. It runs on one 18650. Simple and reliable.
