The product in question has garnered mixed reviews from customers who are particularly focused on its suitability for older homes with non-standard soffit vent hole sizes. One reviewer specifically appreciated the effort made to find vent covers that fit their unique 2.8-inch openings, highlighting the installation process as straightforward when paired with a little silicone for added security. This points to an overall satisfaction with the ease of use and reliable fit for certain applications. Conversely, another user faced a complication with the product's design, noting that the inside of the mounting flange measured 2.75 inches, which caused issues when attempting to use a standard hole saw designed for 2.75 inches. This mismatch is significant enough to affect the installation, creating a challenge for users who do not have the flexibility to adapt the product to their specific needs. Overall, while the vent covers seem to serve a niche market well, particularly for those seeking a hard-to-find size, the discrepancy between the specifications and reality can lead to frustrating installation experiences. **
