Excellent realtor boxes!!
Master lock boxes are easy to use, install change the codes on and can hold multiple sets of keys. Very sturdy and hard to remove if you do not have the combo for the box. They fit on most door knobs or water spigets. Definitely very secure and functional!!

EXCELLENT KEY SAFE
I'm impressed with the design, features, and build quality of the Masterlock Key Safe. The installation instructions are clear, simple, and easy to follow. I decided to place the safe in a secure location near the front door, not on the door knob itself, but rather to a nearby galvanized water pipe. I've tried it out a couple of times and am pleased with the accessibility and ease of use. I was especially pleased with the tough, rubber-type black cladding that protects the case and the sturdy shackle, and there's even a clever, black cover that slides down to access the 4-digit, rotating combination locking mechanism. And I feel the price is reasonable for such a strong, high-quality product.

Very sturdy and very reasonably priced.
This is a very sturdy lock. Very nice appearance, even though you'll want to secure it to a pipe or something low to the ground. It works great and looks even better.

Exactly What I Was Looking For
My choice came down to this lock or the GE "push button" locks. I actually have a GE push button lock, but it is not the mobile padlock version...it is the permanent version that is mounted to a wall. Here are the considerations that went through my mind in deciding to purchase this lock: 1) The GE lock's push buttons can be done in any order. Therefore, as others have stated in reviews about that product line, it is easier to crack, as opposed to requiring a set order. The Master Lock requires a set order, so I like that better. 2) The keys in the GE locks are attached directly to the plate that comes off (fully off) the front of the lock assembly. With the Master Lock, the keys are stored separately in the lock and the front simply comes down but stays attached to the locking unit. I like this MUCH better. I have experience with my GE lock where it is cumbersome to use the key attached to the lock plate. 3) I wanted a mobile version of the lock that could be mounted with a shackle instead of mounting the locking assembly permanently to a wall. The shackle allows you to place it, and relocate the lock, to many areas easily, including a door knob. The GE version holds 3 keys at the most. The Master Lock is advertised to hold 5, but it seems like it might hold a bit more if the keys are small enough. I needed to hold more keys than 3. 4) The Master Lock has a cover that goes up to cover the combination dialers. While it is a small point, I like that the numbers are concealed and do not draw as much attention as if they were not covered. Another benefit of the cover that didn't apply to me because I mounted the lock inside as opposed to outside, is that it adds more protection agains the elements. I installed the lock today over a doorknob...it fits perfectly and securely. The lock feels VERY durable. Another plus that I didn't notice until I received the lock is that the black you see on the sides and back of the lock, as well as the shackle, is a rubber material that protects against anything it touches...very nice! I tested the lock out several times before putting the keys in it, since I saw that a couple of other reviewers had mentioned issues...all is working well so far. Setting the combination and undoing the shackle is very easily from inside the lock. One thing I want to pass on is that the door to the lock won't close if the shackle is not also closed. I was trying to shut the door of the lock while I was putting the shackle over my doorknob when I discovered this. So far, I am very, very pleased with this lock and I would definitely buy another one of these if the need arose.
