Bests & Worsts Reviews from Amazon

Here's why I gave it 4 stars and not 5. First off, this key box does it's job well. It will hold your keys and it does require a combination of numbers to pressed before it will open. It has a solid build that feels like it will last a long time and also feels like it would hold up to any kind of smashing or sawing for quite a while. I think it would take a LOT of work to break this thing open. Now the reason I didn't give it five stars is because it doesn't really have a ton of different combinations to choose from. You can set your code to be any length of numbers. So I could set it to open when I push "7", or I could set it to open when I've pushed 1,2,3,5,6,8, and 0. Or if you wanted to you could set it so you have to push all 10 numbers to open it (not really a good idea). So by now you're probably thinking dang that sounds like it adds up to a crap load of different combinations. Well it doesn't because of two things. You can't repeat a number, and it doesn't matter what order the numbers are pushed in. If my code is 8497, I could push 4987, 9784, 8974, etc. and the lock will open. So to save you the math, there are 1023 possible combinations (I won't bother explaining why that is in this review). Anyone who says differently is wrong, the product description even says "over 1000" which implies it is just a little over 1000. Anyway, the way to set the combination is simple. On the back of the plate there is one screw for each number. Twisting the screw 180 degrees sets that number to be part of the code. So if I want my code to contain the numbers 1257 (remember you can't repeat and the order doesn't matter) then I would simply turn all the screws behind those numbers. If you wan't something easier to remember you can go shorter, if you want the length that has the most possible combinations that would be a length of 5 numbers. Add up the list I made if you want, it's 1023 (see below. I did not count having zero numbers in the code). But don't be scared away when you see how few combinations are possible for some lengths. Remember a potential thief has no idea how long the code is, so he/she would still have 1023 possible combinations to guess from. No one is going to sit there and figure out all the possibilities and then take the time to try them all. And keep in mind that if someone really wants to break into your house and is prepared ahead of time to do so, this isn't going to stop them. This key box is to keep some loser from trying to find the key that everyone hides under a rock or hangs under the deck or whatever. Now you can put that key in a lock box. 4 stars for build quality and the fact that it does what is says it does.
