I love this device to change my bits quickly and easily when I am working.  I really like the one handed operation of it.  My old impact had the quick change adapter as part of it but it was really awkward when trying to change bits with one hand.  Had to hold the drill with one hand while pulling the collar with the other and pull the collar again to put the new bit in.  Not this one.  I can easily push the collar in and the bit pops right out and push the new bit in without having to move the collar.  There was some confusion about what the item looked like because there were different pictures.  I guess one was an older version.  The one I received had the black metal top
