Bought for a new school teacher because of the danger

Easy to use as the instruction.

Really hard to use on most modern hotel locks. I work on locks at a local county jail so I know locks. So it's kind of a crap shoot if it will work or not. When I got it to work, it was easy and great but not on all hotel doors.
