When ordering a door I was offered to install Guardian locks. I had no hesitation about it, I have heard about this trademark long ago. It may be said that we received a set of all basic function for the affordable price. Being a practical and rational person I decided not to save on a locking system. A double protection of my family and my house is much more secure. Besides, in the event of failure of one of the locks the second one serve as a back-up lock. This is the third year I have been using these locks and I can state with assurance that the Guardian locks are an optimal combination of quality and price.
