Answer: 
Yes, but the instructions are sparse and incorrect when stating to use a 3/8" drill bit. The hard plastic insert that is supposed to be hammered into the hole will NEVER fit at 3/8". Really, this is their main business, so I expected better!

Rated 4.3 out of 5 by 21 reviewers.
Rated 3.0 out of 5.0 by Needs polish First: Factory combo cannot be removed. You can set your own tho. Instructions for removing a user-set combination are unclear. Safe arrived in a plain box w/2 stickers (around 4"x6") indicating SentrySafe. Thankfully it was not plastered w/ pictures and things to attract notice during delivery. Safe seems solid and feels substantial overall, BUT, made in China, it needs more attention to detail! (1) One of the two round holes in the safe bottom for attaching it to a floor had poor fit/finish. Namely, the hole in the metal did not align with the hole in the sheetrock-like insulating material. This meant that the washer required for waterproofing would NOT sit flush on the bottom. This basically negated one of the safe's major features. I was able with some effort to shave off enough of the insulator to get the washer installed, but I'm not convinced water won't get in. BEWARE! (2) Bolt-down instructions were sparse, and where it says to use a 3/8" drill bit for concrete, there was NO WAY the hard plastic sheath was going into that small opening. I took some creative license to get it installed, but be prepared for some trial-and-error. Also, BEWARE HUMIDITY, which I was warned about after my purchase. It's apparently not unusual for the humidity inside insulated safes to rise after it's closed and the air cools down on the inside. I measured 71% relative humidity inside after 24 hours (at 70 degrees inside) while my house is 36% RH (at 74 degrees). Apparently some higher end safes include an electrical outlet inside to connect a small heating rod to prevent this problem. This safe doesn't have that feature. So I ordered an Eva-Dry E-333 reusable dehumidifier for $20 to reduce the humidity inside. If I had more confidence in the waterproofing, I would have given this safe a much higher rating. Finally, be very careful registering your safe online. It might sound like a good idea to give them your name, address, factory combination (that you cannot change), and emergency key number, but how well do they protect their web data? Seems like it could be a literal treasure chest for a hacker. March 29, 2016
Rated 5.0 out of 5.0 by Excellent product for our needs. Safe is 3.4cuft. Plenty of space for normal items. Electronic programmable lock, for fast opening, also has a key backup. Safe is carpet lined, shelves are solid, adjustable, not plastic. I think the way it's constructed, the normal house thief would have a problem getting it open, 4live and 3 solid bolts. Lag bolts, to attach to the floor, come with the safe so it won't be carried away. Home Depot was great and close in case there was a problem. They had the best price, in store delivery. Be careful of add on shipping if you purchase online. January 28, 2014
Rated 5.0 out of 5.0 by great safe not heavy enough that you cant move it into position. I liked that. well built. solid. great feel of door and handle. lock takes some studying of directions but is easy once you figure it out.( slid right into the back of my suv)) April 1, 2015
Rated 1.0 out of 5.0 by Buyer BEWARE!!!! Poor workmanship, Poor quality. Safe box locks up and wont open with combination provided. Bad sentry customer service. March 18, 2015
Rated 5.0 out of 5.0 by So far so good I am glad I got this size rather than a smaller one; you always find more things that need to be secured than you first thought. This has only been in place a few months so of course it has not yet stood the test of time, and I rate it on that basis. August 17, 2014
Rated 2.0 out of 5.0 by Average at Best One rack had already fallen off the side upon arrival. Both screws were stripped. Had to repair brand new safe before use. Too big and heavy to bother trying to return. Also safe handle so tight and difficult to open door. May 13, 2014
Rated 5.0 out of 5.0 by Great Safe The product was exactly as expected. It's not too big and not to small, just right June 17, 2014
Rated 5.0 out of 5.0 by Excellent Good! Quality is Strong I Like it. Secure is peace of Mind. July 8, 2014
