Query: BIG disappointment!

We searched and researched. The brand looked reliable, size was good and price was great. The first night we used it, it leaked terribly from dew -- NOT rain -- dew. Followed all the instructions, waterproofed it with the spray stuff. It still leaked. We had a rainstorm a few days later and it leaked like a faucet -- straight from the rain fly. We returned it and were sorely disappointed with this tent.
