The product offers a good price and fast shipping. However, I regret to note that the adhesive is not strong enough to hold securely, as it fell after installation. Therefore, I have decided to return it. Please note that it may be reusable, but the adhesive is insufficient for long-term stability.

Large gap weatherstrip seal works Great!

Works great on my pre-civil war windows. These windows are part of my 180yo home.
