Little pricey, but gave me peace of mind
My boyfriend and I go on vacations pretty frequently, and I hate sketchy key exchanges (i.e. under the mat, in the mailbox, under a rock in the garden). However, sometimes schedules don't quite align and you can't do a hand-off before you leave. If you watch LockPickingLawyer on YouTube, you know that Master Lock is the only real lock box he recommends. It's a bit pricey, but it's well worth the cost if you are looking for peace of mind. Also, it's super easy to figure out. Even if you immediately toss instructions, you could figure out how it works. There are arrows engraved in the metal to remind you how to detach the lock and reset the code.

It works well and is all it claims to be. It's easy to prepare and install. Simple to change the combination and the protective cover over the tumblers works nicely. The lock is very strong, sturdy and of good construction. It is surprisingly hefty and the little number dials move quite easily, even with bigger fingers. It looks like a real lock-- not like many of them that just look cheap and easy to break. The few issues I have are sadly across many different brands and seem to be issues with this style of lock, not just this particular one.
My issues are that ONE, you must turn the number wheels after closing it or it remains in the open position, even though it looks locked. I often find myself forgetting to scramble the wheels thereby failing to secure the lock and essentially leaving it open, even though it truly looks like it is secured. TWO-- once the front is opened, someone could easily remove the entire lock from your door knob, as the latch that locks the handle down is easily visible and quite simple to disengage, allowing the entire lock to be removed when hung on a door knob. THREE--once lock is open, someone with minimal experience with these styles of locks, could easily change your lock code without your knowledge.-- Then you would be "locked out" of your own lock box! FINALLY -- I wish it had a chain firmly attached inside or had some way for you to attach a chain (or similar) to something other than the handle that goes over the knob (too easy to remove it then). The reason is so that I wanted to attach a chain long enough so that one could use the key to unlock the door, but could not easily remove the key from the box (to steal or make a copy, etc). We have different people coming and going, helping my elderly parents (which is why we needed something) and while you can change the combo quite easily, an unscrupulous person could very easily completely remove the key and or lock, thereby entirely defeating the security and reason for dong this. Currently you can only attach something to the hanging mechanism inside the box and once the lock box is open the chain, attached key, or ENTIRE lock can be easily and simply removed or altered.
Other than these issues (common to many similar products or brands sadly), I really like the lock and would probably buy one again as these issues seem to be present in many of similar styles and brands of this kind of product line. This particular one is one of the easiest to use and sturdiest I have found despite its faults. I would probably buy again and would really like to figure out how to wall mount it!

It is very good. I only refrained from giving it a 5 star for the Lock Feature as the introduction of a small window type frame for aligning the opening code numbers can be very useful, especially for seniors who may fumble in getting the desired number aligned in a straight line, especially while accessing AirBnB's. For clarity what I am suggesting is innovation on the lines of the distinctive window frame offered on the narrow edge of four digit Anvil travel luggage locks sold on Amazon. It may require some creative effort to introduce on an otherwise perfect key holder. Best of luck.
