    Rated 4 out of 5 by tstrait from Tons of room Love how roomy this safe is. It is a security safe, not a fireproof safe, which means the walls are just metal with a carpet lining in the interior; no fireproof lining. 3 shelves offer a lot of flexibilty. The battery compartment is of poor design; if you close the safe too hard the batteries will pop out thus making the combo impossible to use. You'll have to use the key to open and reinsert the batteries. Easy fix is to just put a thin piece of cardboard over the battery compartment and now they seem to stay in place.

    Rated 2 out of 5 by John55 from Non durable parts Safe is as expected but I’m unable to replace key hook plate after placing the batteries.. it could be damaged. Customer service is very poor. I emailed several times and called multiple times... no one is responding either way. I’m regretting to purchase it because of irresponsible actions from customer service. Please send me new key hook plate so I can start using my safe and feel like recommending to others. Thanks

    Rated 2 out of 5 by ISafe from Lots of Room, Poorly Constructed The safe has plenty of room on the inside for cash drawers. However, the batteries pop out very frequently. There is no cover over the batteries other than the key hook plate which hooks in over the batteries but is not snug enough to keep them in place.

    Rated 4 out of 5 by TL Army from 6.1 c ft safe Only 1 thing wrong I think, the plastic battery cover/key hanger. Its All plastic even the catches on the back. I got mine home, took off the battery cover, installed battery's and when I went to put cover back on, the plastic latches/hooks brook off. Brand new, not even an hour old. Contacted them about it and they emailed back about me Ordering one. Emailed twice about it, nothing. Without it, battery's don't stay in well. I believe cover should be made out of light metal or at least small screws hold it on, not plastic clips. The rest of the safe is great. No issues with plenty of space. Easy to set my code and adjust shelf's. I like Sentry safes and would buy again, just be real careful of th plastic battery cover.

    Rated 2 out of 5 by Raintree from Office use This safe was purchased for my office about 5 years ago and over the years the push buttons have gotten worn out. We got to the point where only a few numbers were able to work and 5 numbers are needed to program--6 mos ago our Fix it guy called Sentry to reorder the push button pad and we were sent a square pad to fit into the round hole. We provided the product identification numbers and were told that this key pad no longer exists!

    Rated 5 out of 5 by Don85 from Just what I expected. The safe is just what I ordered. I am thoroughly satisfied with the product. I am not satisfied with the shipment. YRC was a terrible transit company with this delivery. I purchased this safe on June 22 and you shipped it on June 22. It arrived in Phoenix on June 24 and moved from truck to truck in their yard for eight days until it was delivered to me on July 1. Terrible handling.by YRC transit.

    Rated 4 out of 5 by Roger from DC from Hard to set up but works well The instructions were not very clear, making the safe harder to set up than it should have been. It also had a broken component on arrival (the plastic internal part that covers the battery box and holds keys). Once set up, the safe itself works beautifully and now (so far) seems very easy to use. My only other issue is that despite the implication that the safe is water and fire safe, I do not think that’s the case with the model I purchased. I emailed customer support to confirm this but have not yet received a response.

    Rated 5 out of 5 by Safe David from Good looking safe The T0-331 is good size safe. Any larger it would weigh too much to handle by my self. I placed large felt pads under the safe approximately 8 of them. I used a hand truck to move the safe in to the house. Once in the house I was able to slide the safe with ease. A little preparing a head of time sure goes a long way in how and where you place the safe. The safe did have a chemical smell, but I can tell it’s easing up a bite. I read on line the batteries kept falling out if you closed the door hard. Since the inside of the safe is lined with Berber Carpet, I place a piece of Velcro over the batteries and that alleviated the problem. Box that safe came in was a little beat up and once I unboxed the safe it looked great. Very please with over all experience.
