The L-1172C National Mailbox Lock Replacement has garnered a mixed reception from customers regarding its functionality and ease of use. Many users appreciate the affordability and ease of installation, praising how straightforward it is to replace the old lock cylinder. For individuals looking for a cost-effective solution for public mailboxes, several customers found it to be a great buy, with one stating they would purchase it again due to its effectiveness. However, some users expressed significant concerns about the product's quality and design. A recurring issue was the lack of a suitable latch, as the new cylinder only comes with keys and does not include a new latching mechanism, which led to frustration for those whose original latches were damaged or bent. Key insertion was another common complaint, as customers noted that the keys were difficult to maneuver into the lock, requiring a specific angling that added to the inconvenience. Additionally, some users were skeptical about the product’s USPS approval, indicating a disparity between what was expected and what was delivered. While the lock does serve its basic function once installed, the overall customer experience suggests that buyers should be aware of its limitations and potential quality issues. **
