I wanted to let you know that I went on a welfare check on my 1st day back at work after being in your class. Sure enough, neighbors called concerned because they have not seen the older male neighbor in over a week. They asked for a welfare check at his rent home. Long story short the property owner gave consent for me to make entry. I thought to myself, ‘well there is My Sgt., a neighbor and an animal control officer all watching me. I am going to look pretty funny getting these tools out if I fail!’ NOPE, I smoked the knob fast, 45 seconds maybe, then the deadbolt was locked, smoked it also bout 45 seconds. Sgt. was very impressed, and later told me he was worried it wouldn’t work, but it did thanks to your class AND HOLLOTEC!
