Rated 1.0 out of 5.0 by Never buy this would not let you get the key out when you locked it I tried 2 of them and nether one worked February 17, 2015
Rated 5.0 out of 5.0 by Good purchase Works great. Easy to install.. The hardest part was catching the postman to open from that side. August 12, 2014
Rated 5.0 out of 5.0 by Perfect! Had to replace our mailbox lock and I find this lock more secure than the previous one. Installation was pretty easy and the price was great! Overall I would recommend this product. October 23, 2012
Rated 5.0 out of 5.0 by It works better and fits tighter than the original lock on the mail box. The lock was easy to install. It was more secure than the original and did not rotate slightly when the key was turned as the original. The key is made with a more substantial material than the original. Product. Which means had the original product been made properly I would not have had to buy a replacement. It came completely apart the last time I opened it. December 8, 2011
Rated 5.0 out of 5.0 by Great price works 3 minutes to install. Simple. Good for what it does. June 18, 2014
