Great safe!
It’s great! No complaints other than the latch sticks a little. But if I push down on the top as I’m opening it, it opens easily. It holds quite a bit of stuff and seems very well built. I do recommend.

Combo safe would not open (even though the green light was on) so we had to "bust' the safe to open!
I am so disappointed. I shopped forever and finally found the perfect solution but unfortunately, it did not perform as advertised. We set up the code, tested it and it worked so we loaded it with all our important documents and then, it would NOT open. The code was right, the light turned green we heard it "release" but I could see the metal latch in the seam between the top and bottom and it would not unlatch. I called customer service and was told it happens sometimes and we just needed to put weight on it for 24-48 hours to compress the seal and then it would open. We put 75 lbs of weights and waited 48 hours and it did not work. I called again and was told it was probably the battery so we bought new ENEGIZER batteries (not Duracell) as instructed, and it still would not open. The CS rep was great and stayed with me on the phone as I was pressing down on the lid waiting for the "release" then pulling up on the latch but it still did not work. So bummed. We finally found some info online that explained how to "bust the lock" which we did in order to get our documents out. Now I have to return it and will not order another one. We waisted HOURS trying to make it work and my time is worth more than all this hassle.

My initial delivery had a problem opeing
The initial order for this safe arrived with a problem that has been reported previously that it woudl not open. Called tech support who recommended that I apply a heavy weight to the top of the safe to loosen the waterproof seal. I did this an was able to open the safe. To test it, I closed it again and was unable to open the safe. I returned the safe and ordered another one. This one had no problems opening. (important: When you put in the code and the lock mechanism opens, pull up on the far right of the open mechanism to open. Not an obvious to do). The new safe is exactly what I wanted.... a fire and waterproof safe for important documents and digital media.

This is a serious fire safe
It is very, very heavy. Lifting it out of box and into position was not easy. But it is rock solid. Read instructions carefully to understand battery installation. Programming your own code is easy. It is tricky to open -- you have to put in your code and then quickly push down on the top as you squeeze up on the opening lever. I usually need to do it more than once to get it open but I do feel it is secure and it's roomy enough to hold all my important items/documents.

Great safe, extremely sturdy
Only worked a few times now is refusing to open with my paperwork trapped inside so I can't even return it, beyond frustrated Update: after all the troubleshooting what worked was tapping it with a rubber mallet as they suggested to dislodge any stuck mechanisms, then it easily opened the first attempt, I changed my star rating to a 5, it is a great safe 👍

Could not get it opened X 2 units
Bought one here, to replace a Sentry Safe unit that I had for several years until the top came off. Replaced it with this one with the digital combination lock. Bad decision. I was able to open the unit one (1) time, because it came unlocked. As soon as I shut it to try the combination they provided, it was clear that it wasn't opening with that combination. It made a noise that sounded like something was moving in the lock mechanism, but whatever may have been moving in there wasn't enough for me to get the lid opened. When I looked closely, I could see that the mechanism involved a "hook" and what I would call a "latch bar." The design seemed to be such that you should be able to press on an exterior bar to get the hook to pivot enough to not get caught on the latch bar, probably the latch bar was supposed to move away from the hook when the correct combination is entered. I tried a bunch of times but never saw that latch bar move at all and while it looked like the hook pivoted some it was not enough for me to get the thing opened. So, I called the manufacturer, I figured I just had the wrong combination and since the combination was six digits I didn't really feel like trying literally 1,000,000 combinations to see if that was even the problem. I have to say that the manufacturer was great about it, they didn't think it was the wrong combination, they thought it may be a flaw with either the mechanism itself or possibly the seal was somehow interfering with the mechanism. So, I tried what they suggested, but to no avail. I called them back (the person I spoke to gave me a direct dial number which I thought was outstanding) and they sent me another one and told me don't bother returning what I paid for. Guess what happened with the one they sent me? Same thing, opened it once, tried to open it again with the combination they provided, it didn't open. I called the same agent again, she offered to send another one, but I declined. I purchased a different model from a different manufacturer and made sure that it had a key lock rather than a digital combination lock.

Heavy Duty
The Lock Box is well made and heavy duty. The digital lock worked well. My previous Lock Box malfunctioned with key, so the digital lock was a lot simpler and won’t break.
