“We had a home invasion last year when our French Door was kicked in and we found it difficult to relax in our home for many months after that. Initially, we installed three sash locks to secure the door until we discovered from a local fire marshal that they are a fire hazard. Fortunately, at that time my brother had installed a Burglarybuster 3 and recommended it to us. Since installing this magical device we now feel a lot safer in our home.”

“Well what can I say other than thank you for your advice and let you know that your device has been a blessing. Over the past few years we found a way to secure all our doors and windows with the exception of our French doors and this was always a big concern for us. Since installing your Burglarybuster we all feel more secure in our home.”

“We want you to know that we LOVE these and that we already have installed three. I am telling all of our neighbours about them. I hope they are ordering them. Not only do they protect against burglary BUT they also protect against the strong gusts of wind we get from living in a canyon. We have many French Doors in this house and only had these on the ground floor. These extra five that we ordered are for the French Doors on our upper floor. Recently some of the French Doors burst open during a strong wind storm. The doors that had the Burglarybuster 3 on them held strong against the wind. Thank you for inventing such a good product that looks good as well!”
