Review: Great for keeping mail dry - I've had issues with my mail getting wet/soaked whenever there was even a little amount of rain. This solves the problem by keeping mail elevated from the bottom of the mailbox. Highly recommend.
Review: Does its job keeping mail off the damp bottom of the mailbox - It works and is of a decent design. I don't like the sharp edges in the front so suggest that a redesign have a ramp to cover those edges. I also put two screw through it to anchor it to the mailbox and to help it keep it's shape. I like that it is easily expandable to fit different sizes of mailboxes.

### ⭐⭐⭐⭐⭐ Keeps your mail dry
*by S***K on May 9, 2026*

Perfect for our need. The mailbox is cemented in and the top mortar had cracked thus got a leak over time. When it rains the moisture collects along the bottom thus pooling and wetting the mail. This has made a huge difference and keeps the mail dry.
