SentrySafe 7250 Waterproof Floor Safe, 540 Cubic Inches, Gray

The hardest part is breaking the cement. I rented a saw from Home Depot for $119.00 for 4 hours that had a water hose attachment, I didn't turn the water on very hard because I didn't want to flood my house, the saw cut the cement pretty easy. I made 4 vertical cuts, no horizontal cuts...I couldn't get the saw in a position to cut horizontal. So after I made the cuts, I hit it with a hand sledge hammer (short handle like a regular sized hammer, big head) and cracked it and eventually got all the cement out. The instructions say to dig the hole 21" however, that was too deep by about 5 inches, I had to dump a bunch of dirt back in and add my own rocks at the bottom. Even though my hole was smaller than the recommended 16 x 16 it still took 3 1/2 80 lb bags of cement. I didn't get the quickset because I wasn't sure how much cement if would take and wanted time to mix one bag a time. Make sure you level the top of the safe with the sides of the uncut floor. All together it cost me $220 with a little labor time and my safe looks great. I don't mind the combination taking a while to get in-It works fine if you do it right, It took me 2 try's to get it to open. No problem. This is the best deal for the money!

Decent quality. Great for the price. Easy to install if you have the tools. Water tight if you can tighten it all the way. 4 numbers can be a little tricky.

For the money this is a decent safe. You just need to prepare it properly before embedding it in concrete. Several reviewers complained that the tumbler mechanism corroded. There will always be moisture under the concrete slab so you must use the heavy plastic bag they supply with the safe to make sure that no moisture gets in from underneath the concrete. I actually went a bit further than that by first wrapping the sharp corners of the base with foam padding so they would not puncture the plastic bag. I also used silicone sealant to seal the bag around the collar of the tube to make sure that vapor didn't even get in. After installing it I sealed a humidity meter in the safe for a couple of weeks before actual use and it registered only a 2% increase in relative humidity but I think that was due to the temp inside being slightly cooler rather than an increase in actual humidity. Another thing I highly recommend is storing anything sensitive to moisture in a waterproof box. As others have pointed out, the plastic cover appears water tight but would melt in a NY minute in a fire. I use a few Plano model 3440 boxes. They are cheap, waterproof and stack up nicely inside. I store backup 2.5" hard drives and they fit inside the Plano 3440 perfectly. Final comments... Use a bit of red paint or nail polish to make the tick mark for the dial more visible. Also, this is really only a 2 number combination in practice since the 3rd number has an extremely loud and obvious click, and the dial will then actually rotate on its own to the 4th number if you let go of it.

What can I say. It's a SAFE. It's easy to use. Works as described. Guaranteed no one will pick this up and run off with it. If installed properly, this thing ain't going any where. I can't attest to whether if it's Water resistant or not, or if it's fireproof or bombproof. But it works. I feel confident that it will keep my valuables SAFE. For the price. It's worth it. Honestly, not that convenient to get things in and out of it. If you want convenience, you will have to sacrifice secrecy. Point of having the safe in the ground is so that no one knows where it is and it's hard to pick up and run off with it. If you want to keep couple hundred bucks safe in the house, you can get a wall safe or a heavy gun safe to keep your cash in it. if 2-3 guys break in your house, they will find it, pick it up, and load it up and it's ALL gone. Not worth it. Go with the inconvenient ground safe.

This safe can be good or bad depending on your needs: Pros: * sturdy steel body likely to hold up for many years. Some dont like that it isnt hardened steel, but I am not sure that is relevant in a safe meant to be cemented into the ground. * lid is interchangeable. This could offer a few advantages over the swing open designs, especially if you damage the locking mechanism or internal tumblers. * plastic lid screws down with indented grips not very visible in the picture. This seemingly creates a nice water resistant seal, but i havent tested it yet with sponges and a bit of water poured onto the seams. Negatives: * This safe is a pain in the ass to open because of the 4th digit. Lots of reviewers talk about the time to open the safe and dont say why, I'll elaborate for them. You have to turn the dial past 0 four times to the right for the first number, but only pass the second number twice and then land on it, back the first direction again passing the number once, then finally just place the dial onto the last number. Have a light handy, because the lid is sunk in and the line to match the dial isnt painted, just a dent. *The four combination lock over the three combination is worthless. After you pass the second number, the last two clank the dial so hard that it isnt hard to guess if you didnt know. You only really need to know the first two numbers, and really only the first and how to spin the dial if you have good hearing. *Non-hardened safe means that someone skilled with regular shop tools could easily open this. All that being said, this safe is perfect for my needs. First I am considering the fact that this safe is hidden, and you do indeed need tools to open it without the combination or knowing the weird way to spin the dial. If someone has broken into your home, knows where your safe is, and has tools to do the job, you've already messed up somewhere along the way, unless you have a rich home that screams 'rob me.' This safe is more about keeping trespassers completely unaware that you even have a safe as well as your low level brick through the window robbers. Those kinds of thugs dont carry tools, they are just looking for whatever they can get. So this safe could be really great deal for the price or a piece of junk if you need to safe guard some family jewels. Last thing to consider: * Safes are an upgrade that will increase the value of your home if done correctly. If you are going to really take the time to jackhammer your foundation and seal this safe in, perhaps spending the $600+ on a nicer one isnt as expensive as it seems on paper. Having a nice inlaid safe to the home you are buying is a definite bonus as a buyer and could land you extra money later on down the road, IF the safe is a nice quality. My safe isnt personally going such a route, I have plans with a 100 pound clay potter and 3 bags of cement and a removable shrubbery going on top.

I like it. Hard to get combo right but thats a good thing. Everyone should have one and keep their paper bitcoin wallets inside.

Great product Fast and as promised Thank you
