I've used Supra box's for years, I first became familiar with them in the auto industry for vehicles and they preformed excellent in all weather conditions and we always knew where the key were. A few years back I put one like this on my house so if I was running late I could call a neighbor to let the dog out and they never had to worry about looking around for a key !
I now have a property management business for private homes and include a Supra brand box as part of the service, I never have to worry about forgetting key's and the same goes for the owners plus the combination can be changed anytime in less then a minute some have even given the code to Law Enforcement/EMT's in case of an emergency.
In today's world it's hard to put a price on peace of mind let alone your security !
Why would anyone go digging around in the dark and possible cold looking for a key that just might not be there ? I've had more then one person comment on how it looks like an alarm system, and they make an excellent gift that shows you really care.
Trust you will not find Supra Lock Box's cheaper anywhere else then Amazon.com
