Rated 4 out of 5 by Phredddd from Good product Disappointing service So far I am happy with the safe, I am disappointed in the instructions, website, and Contact. The instructions tell how to bolt the safe, my model did not come with the hardware. The instructions, say to get more info on the website. I spent over 15 minutes and cannot find the recommended bolt size. I went thru the contact us form on their website on Sunday, and as of Tuesday night still have no idea what size bolts are recommended. Hopefully I will not need customer service in the future. I always felt Master Lock made a great product, have never needed customer service, and if this is any indication I hope I never do..

Rated 3 out of 5 by BelRidge from Strong The safe had been closed and never open with money and documents stored inside for at least 4-6 months. When opened all documents was mildew smell and wet.

Rated 5 out of 5 by Kelly512 from Love it! I’ve been wanting to purchase a safe for a long time, but always put off because of the hefty price tag, but I decided to just bite the bullet and go for it since I figured I spend so much money on other frivolous items. The safe is worth every penny. It looks great and is super easy to set up and has just enough room for all of your important documents. I’d definitely recommend this safe to others.

Rated 5 out of 5 by Doverchipmunk from No more safe deposit fees We have paid annual fees for many years for storing important documents and valuables. We researched home safes for security and protection in case of a fire in our home. We believe that the product that SentrySafe has provided will give us the security and protection we need for slightly more than 2X the annual fee for the safety deposit box and we have access to our documents 24/7.

Rated 3 out of 5 by smithcos from New safe Not a bad safe, but I wish I make the light work inside and I REALLY wish there was a way to bolt it to the floor. It's not necessarily "safe" from robbery when it can be picked up and hauled off by hand by a single person. Thats why there should be an easy way of bolting it permanently to a hard surface, like the floor or a cabinet.

Rated 5 out of 5 by Ynot from Safe Feeling With this purchase we feel safer about storing our important documents against fire. The safe was large enough for our documents and easy to operate. Being able to add a combination that we could remember is a plus. The size of the unit made it easy to find a place to locate without taking up a lot of space.

Rated 4 out of 5 by Toddk from Good value I like this safe a lot. Its a good size for my needs and the price is very reasonable. My only issues with it are that I cant turn off the keypad sound and after I bought it I found out that it is easier than I expected to bypass the electronic keypad. All in all it suits my needs very well.
