    • High Quality, Heavy Duty Safe
Style: 2.2 Cu. Ft. Home Safe Pattern Name: Safe
Excellent safe - very pleased with this purchase. After looking long and hard for an adequate safe for multiple pistols I own, I came across this safe by chance, and overall, it had everything I wanted. Other safes I was looking at were quite small, looked flimsy, and even though they featured biometric capability, the user reviews left me very unnerved - some being broken into by children, while others being broken into with a firm strike with a fist. I am sure such stories were rare, but the fact that such incidents occurred left me highly wary of making a purchase. Not only is this safe larger than most within this price category, but the door and (4) bolt locking system is very robust. I was very pleased to see how solid and well built everything looked, and the heft / weight of this safe leaves me feeling confident that my firearms will be kept safe from curious children. Some users mentioned the carpeted shelves being flimsy and easy to give way. Yes, the shelves are very basic, but I had no troubles securing them in place with several firearms worth of weight that did not cause them to tilt or break free. Further, they are adjustable, allowing you to place them in differing areas, based upon your storage preferences. The locking mechanism feels very robust and stout - you can feel the (4) heavy duty bolts locking firmly into place, and the door has a nice solid heft to it as well. As for the keypad, it was very easy to program, and is very easy to use with soft push button keypads that allow you to input a (5) numerical code - everything except "00000", which would be ludicrous to use. I prefer this numerical keypad style of entry versus biometrics, as the more I read about biometric access, the less certain I felt. I am sure there are some excellent biometric safes available, but I simply like the basic numerical entry - safe, simple & effective, especially if you need access without fuss & bother. One of the features I like about this is the fact that if an incorrect code is inputted more than (3) times over, the system will lock out for a full (2) minutes, which will discourage a curious or malicious person trying to crack your code. In terms of security, this safe can be bolted down to the floor, which is wise to do, if you have the means to do so. The included bolts are very heavy duty, and would be very effective in keeping anyone from removing this safe from your residence. Without the bolts (despite the 100+ lbs. weight of this safe), a malicious person could pick up this safe and walk away with it - demonstrated by the fact that our FedEx driver carried the safe into our home. Access can be made with the keypad code that you enter, or in the case of battery failure (or forgetting your access code), the safe comes with (2) skeleton style keys. What I like about the keys is the fact that the key entry is 100% hidden behind the removable keypad, which is not obvious at all. One would have to be knowledgeable about this feature to utilize it correctly, so I really like this hidden aspect. However, it is highly prudent such keys are hidden with great care, as curious minds could easily ascertain this information with a basic Google search. So, if you have young children or teenagers alike, be 100% sure this set of keys is in a locale they could never find - with them, access to the safe is moments away. One aspect that would be nice is interior LED lighting, as it is quite dark further back into the safe itself. However, you can easily find auto illuminating LED's for this very application, so this is an easy add-on to a well built safe. Overall, I am very happy with my purchase. I feel confident that this safe will vastly discourage anyone from gaining access to my firearms, and I trust that this layer of protection will keep my family safe, as I always want to be as responsible as possible when it comes to firearms - especially with curious children who simply do not know better, no matter how much they are taught or drilled. Whether your intent is to store firearms like me, or other valuable possessions, I feel that this Sentry Safe is one of the best on the market when you break down the size, pricing and features. I am very happy with my purchase, and look forward to utilizing this safe to its fullest potential. ... show more

    • Highly recommend!
Style: 4.7 Cu. Ft. Fireproof & Waterproof Safe Pattern Name: Safe
Very durable and worth every penny. Set up instructions were very simple to follow. Plenty of space inside for our possessions. A dial lock would be preferred over electronic but it comes with back up keys which is nice.

    • Very poor quality…
Style: 4.7 Cu. Ft. Fireproof & Waterproof Safe Pattern Name: Safe
The only thing positive I can say about my order is that Amazon is fantastic. The safe is another story and SS should be ashamed to allow something like this to leave their factory. Here is the list of reasons why. 1. waterproofing gasket that should go around the entire inside edge of the safe door only went 2/3rds around the edge and the edges of the gasket look like it was torn by hand. 2. the fabric on the inside of the safe looks like it was cut out by a child, is not fully glued in place, and is falling off both the safe and the flimsy sheet metal shelves. 3. shelves are made from flimsy sheet metal and fabric is falling off. 4. the rails that support the shelves are screwed in place, but they are not screwed all the way in! 5. the paint on the top outside edge of the door (left side) is scraped down to the bare metal (not a huge deal on its own but combined with 1, 2, 3 and 4 its just adds to the list of unacceptable quality characteristics) Amazon was super helpful and set up a return pick up and offered to replace it; but I'm going to find something that has a different name on the front of it. Thank you Amazon! ... show more

    • High quality and spacious safe with one major (but correctable) design flaw
Style: 2.2 Cu. Ft. Home Safe Pattern Name: Safe
I don't normally write product reviews, but felt compelled to review this safe. I own another (deposit style) safe from Sentrysafe and have been very happy with the overall build quality. I was looking for a slightly larger safe that offered more organization and usable space. This safe is very high quality, sturdy (and very heavy--100lbs). It has several very useful features including soft inner light, backup key access, and carpeted shelves. **If you read the reviews on this safe, I think most would agree on the superb materials, fit, and finish. Many of the negative reviews point to a flawed battery compartment design. The battery compartment for this safe is located on the INSIDE of the safe (as opposed to behind the keypad on the OUTSIDE of the door). This means that the safe needs to be OPEN to change the batteries. Unfortunately, there is a significant gap between the battery tray and lid so closing the heavy safe door can dislodge the batteries and disconnect the circuit, rendering the electronic keypad unusable and you will need to use the back-up key to manually open the safe. This completely defeats the purpose and convenience of the electronic keypad altogether. Some people have reported a few jerry-rigged solutions like inserting a piece of cardboard in between or taping the batteries in place. I had some extra furniture foam pads (the kind you stick under chair/sofa/table legs etc... (to prevent scratching hardwood floors) and stuck a few of them across the inside of the plastic lid cover. This eliminates the gap and secures the batteries in place when closing the safe door regardless of how (reasonably) hard I tried. Problem solved! I totally agree that this is a major technical fail in the engineering and design of an otherwise extremely high quality safe. I took a chance with this minor modification and couldn't be happier with the final quality and value of this safe! ... show more

    • Works fine with minor adjustment
Style: 2.2 Cu. Ft. Home Safe Pattern Name: Safe
It's a functional digital safe with a good size. You can use the shelves or remove them to fit larger items. The complaint about the batteries is real---without some additional support, they slide out of place, requiring the use of the key to open. I was able to fit some thin foam between the batteries and the plastic cover, and I haven't had any issues. At 100lb, it's a bulky safe that would take some effort to walk off with, and I can fit it inconspicuously out of the way. For its price ($250 total) and size, it met my needs. ... show more
