just finished up year two with the 4x6 fiberglass blind I got from Redneck Blinds. It's the 10 foot elevated blind. All windows have rubber seals and all are as new. No water gets in, other than a couple of drops. Door has a soft rubber seal all around the edges. Squirrels have nibbled at a lot of it, but haven't been able to damage the seal to the point that it won't seal. Never a wasp inside. The flip up glass windows, which were my minor complaint, are fine. I had minor gripes about the windows having to be up or down, with no middle ground like you can get with sliding windows, but it's worked out Ok.
I like it.
