Review on Effortless Mailbox Enhancement: Universal Peel and Stick Replacement Mailbox Flag (No Tools Needed, Fits All Mailboxes) by Tim York

At first I thought the quality is good, the flag is metal etc. However, I bought it specifically not to poke a hole in the mailbox boundary. It stuck to the bricks until the first rain, and then I found it floating in the sewers along the road. The glue will probably not withstand any weather and is therefore unusable. Update: I contacted the seller and he responded very quickly. A new"updated" version was sent. I'll update my review once I see how the new version holds up. Received a replacement for "reinforced glue", same thing happened when it rained it fell off. Bottom line, the glue won't stick to weathered bricks. I ended up using FlexGlue so far so well. He survived the downpour of the first day.
