Thread may have been dead, but I came across this in the search as I purchased my own set and they arrived not but 3 days ago. I have since picked Every lock in the house (about 15, including a door I picked and stole the lock from) basically having these see through locks, can't hurt, but I just took my time and got the locks open in a few minutes on the first try with visualizing the lock insides.
There genuinely is no rush like doing that for the first time and sitting in disbelief at how easy it is to get into houses.
