As almost everyone else has said, the product is well done and works well. The included screws stripped out almost immediately. Do yourself a favor and go buy three, 3-inch stainless steel screws at the hardware store and use them instead. Four stars because I think for the price they should include better screws.

I rarely write reviews but I thought it might help others if I shared what I learned having recently installed and used this product. I originally heard about the Door Bull on a DIY Network (now known as Magnolia Network) TV show. It sounded like a very intriguing product and it would provide me with more security protection and peace-of-mind. I have been waiting to buy it hoping it would drop in price like it did late last year. It has not changed price in some time so I finally made the decision to buy it at the current price and not the sale price. As other people have already mentioned, the mounting hardware, specifically the mounting screws and drill bit provided inside the box, are low quality. My best guess is that the screws are a low quality zinc. I decided to use my own 1/8 drill bit. Even knowing that the mounting hardware was low quality and being extremely careful (e.g. pre-drilling holes, setting my power drill on the appropriate torque setting, taking my time, etc.) I also almost stripped out some of the screw heads. I used a PH2 phillips screw bit (shown in photo) and it seemed to fit the head of the provided 3 screws the best. In my photo, it shows that I had to mortise the main Door Bull mounting bracket into the door jam. Using a sharp wood chisel, it was actually not very difficult. I simply held the main Door Bull mounting bracket up to the door jam, used a pencil to trace around it, and then chiseled it down to the right depth (approximately 1/8) so that the mounting bracket would be completely flush with the rest of the door jam. If I did not mortise it out, I would not have worked on my door because there was a very minimal gap between the door and the door jam which is really great for keeping the weather out but made it so that I had to mortise the Door Bull in or it definitely would not have worked in my situation. The Door Bull comes with a total of six 3 low quality zinc screws. Three of them are for the main Door Bull mounting bracket and three of them are supposed to be used to swap out shorter screws in three of hinges on your door (opposite side of door than where Door Bull is located) with longer screws which is a great idea. When I started swapping out the screws that were in the door hinges and screwed into the door jam, I was shocked to see just how short most of them were. In my photo, the far left 3 screw is what comes inside the Door Bull box. The middle screw is what was holding my door to the door jam and those screws were only 3/4 long. A 3/4 screw in a hinge is really more for just looks and it seemed like an angry toddler probably could have kicked my door in on the hinge side. After seeing just how short the hinge screws were, I went down to my local hardware store and purchased several 3 wood screws (far right screw in my photo). I replaced all the 3/4 hinge screws with the longer 3 wood screws. Again, the Door Bull provides you with a total of three screws to replace one screw in each hinge with a longer one but I wanted even more protection and my door had a total of 4 hinges. If I was going to all the time and effort to buy and install this product to improve security, I wanted to completely do it right and not leave several 3/4 hinge screws as the weakest part of my entire door. The quality of the actual main mounting bracket and the part that slides over it when in use (w/ the Door Bull logo on it) is good/decent quality. They are both made out of aluminum and I have no issues at all with the quality of those parts. I also appreciate that the Door Bull got me to check the door hinge screws since they provided three of them otherwise I probably would have had no idea just how short the door hinge screws were in my door. Using the Door Bull feels very solid and I have to say that I do believe that it has improved the security of my door. I previously had a cheap white flip latch on the door which is better than nothing but it really is not designed to provide much security protection from someone who is deliberately trying to force their way into your house. The Door Bull seems like it will do a much better job and my hope is that it never needs to get used in real life but I do have trust that it should do what its intended to do. For something that costs this much money and is designed to help improve the security of your home, the Door Bull really should come with higher quality mounting screws and a higher quality drill bit. I would really like to see them include something like stainless steel screws rather than cheap zinc screws. It would also have been great if they would have provided extra additional hinge screws (more than just 3) but as I mentioned, at least they got me to check those which I do appreciate. The Door Bull wouldnt work as well with extremely short 3/4 hinge screws holding the door to the door jam. An entire vertical side of the door (opposite side where the Door Bull is installed) would definitely have been the weakest point of the entire door. After replacing the short 3/4 hinge screws with 3 screws, I now have much more confidence that the security of my entire door set up has improved significantly. I gave the Door Bull 3 out of 5 stars specifically because of the cheap mounting screws and cheap drill bit. Had they provided high quality mounting screws and a drill bit (which is really what they should do for the price that they are charging), I would have given it 5 out of 5 stars. The other option would be for the Door Bull to significantly reduce the price of their product to correspond with the cheap mounting hardware provided. Since this product is designed to improve security, the right thing to do would be for them to make sure that all of the hardware provided is high quality. Update 11/5/19: The creators of The Door Bull have said that they are changing the screws to Stainless Steel screws based on user feedback. Once I find out when the change in production happened (or will be happening), I plan on updating my star rating on this product accordingly. Thank you Door Bull for reading our feedback and taking real action to make this product even better! It’s very much appreciated. Update December 2022: Updating my rating to 5 stars for two primary reasons: 1. They are now including high quality hardened metal screws - thank you Door Bull creators! 2. When I originally purchased the Door Bull, when it initially became available, it was $69.99. That cost seemed very high considering the amount and types of materials being used. I see the price right now is $27.99 (possibly a temporary sale price) which is less than half of what I originally paid and that lower price seems much more reasonable. After using the Door Bull daily on my front door for 3+ years, it’s still holding up great and it looks and functions as good as the first day it was installed. After writing my original review, I did purchase/install 1 additional Door Bull for another exterior-facing door on my house. I still strongly recommend this product.

Lets face it locks are for honest people and if someone wants to get in your house they will. What your really trying to do is buy time and this device will do that. I have glass on either side of my door which looks great but makes it easy for any would be theft. This device installed above the dead bolt and regular lock will add the additional problems for anyone tryng to jam the door open. The extra long screws to use in the hinges is also a great idea. Bottom line easy to install, very sturdy, if your looking for added security you found it.

The Door Bull was fairly easy to install. The trickiest part is lining up the frame plate to protrude just far enough to slip the lock over. After you drill the first hole and position it make sure to close the door and test if the lock slips snuggly on the frame plate before you drill all 3 holes. You dont want it too loose and my first attempt I had it too far in so i could not even slip the lock on at all. The screws were high quality stainless steel. Had to apply a fair amount of force putting a couple screws in but the heads did not strip which is a sign of a quality screw. Three extra 3 screws are provided so you can fortify each of the three door hinges mounted in the frame with one longer screw. I was amazed to find the standard hinge screws are only about 1 long! My molding protrudes a bit so my lock is at a slight slant to the door but it is snug and slips in snugly. I dont plan on trying to kick my door and test this so I cannot verify how well it works but the concept is sound and if anything it may discourage an intruder or slow them down enough so you can arm yourself.

I read the other reviews and complaints about the screws that are included in the kit, and decided to get my own star headed 3 screws. I like mine better than what comes in the kit. I ended up replacing all of the screws in my door hinges (as shown in the photo, a 2 yr old could kick in my door), and used them for this Door Bull too. It fits well against the door, and there is no slack, its snug, and easy to slide in and out of the groove. For a little more security, its worth getting one of these, especially if you dont use your front door very often. However, if theres a power outage, and you dont have a battery backup on your garage door opener, then you are not going to get in your own house through the front door if this is in place. Common sense, sure....but theres always somebody that will forget.

I have an alarm system, but… I don’t care WHERE you live, you can’t assume that you’re safe anymore. I’ve used these to create safe rooms inside my home, or to just slow an intruder down. By the time the bad guy gets past this device, I’ve grabbed my phone and escaped via a window.

Would recommend this for added security.
