Question: How long do the batteries last?
Document: It's a good buy as long as you know about that shortcoming with the pop-open door, in advance.
I still use the original batteries it came with! I would trust that anything in here is safe.
Nice product. I especially like the key to enter if I forget the code or the batteries got out. I only wish they had put four holes on the bottom and the back to install the box against the wall and/or floor.
I just got this and installed it. Very simple instructions work just like they say it will. For an inexpensive safe I give this guy a 5 star. It also comes with batteries installed, at least mine did. Nice packaging too. I am very satisfied with this and happy I that I just dont hide my valuables in a coffee can.
I bought a safe to keep my valuables protected in my college dorm because I was without a key for a while and left my room unlocked more than I should. It was a great safe, did the job; but I never found the keys that came with it and I can't find any contact info for the seller (Sky Enterprise USA). Still trying to get those keys because I'll be heartbroken the day the batteries die.
This safe is super amazing. I bought it to keep my money safe that earned from my restaurant job. It comes with a manual, two keys, and screws for mounting. I received the safe with batteries installed already. It is very easy to program in a code and use other features of the safe. My only complaints are that the buttons when pressed make an obnoxiously loud beeping noise, and there is no wire for looping the safe somewhere securely.
I have 3 grandsons in the same family, ages 6,8 and 11. They were constantly bickering about who took what from whom, so last Christmas I purchased one of these safes for each of them. They put all of their little special toys and money in their locked safes. Now they are happy and the parents say it was one of the best gifts they could have gotten. It has a combination and keys.
this safe is perfect, great buy, and the perfect size, and the loud beeping noise that some dont like, I like it, it will let me know if someone is trying to get in the safe, you wont regret buying this safe, love it,
quality is great with a reasonable price. Was exactly what was advertised. No problems with this order. I'm completely pleased.
great service. I love my new safe, it works perfect. would recommend this merchangt to any one!!! i would definitely do business with them again.thanks
