This is a string and on the whole well made safe. It is slightly let down by a flimsy battery cover which had to be replaced on mine. This is a heavy safe, so will take several people to lift it.

It turned up on time and was well-packaged. The instructions were easy and I fitted it into the floor without any problem. I like the fact that there is a manual key backup, in case the batteries die. Overall, we have been very please with the quality and size of this product and highly recommend it.
