I agree with you Rich, great video. I don't own a pocket hole jig. I've only used one at someone else's workshop. My conclusion is they are very quick, they can be accurate if you allow offsets on your joint to allow for movement when tightening. Great for unseen fixed framework and panel work like you have demonstrated. A good time saver for production runs using low skilled labour to save machining joints. They are strong enough in the right place and great for beginners who can achieve their goal quickly.
