[EX Q]: My husband and I didn't have time to attend an 8 hour birthing class at the hospital, so we opted for this video. It was very informative and helped us understand what was happening when we went to the hospital. It was a little cheesy, but definitely worth getting.
[EX A]: Positive

[EX Q]: I bought this for a narrow entry tiled shower. It was very hard to find a tension bar that would work for my 26" shower opening - not to mention I wanted a nickel or chrome finish. The bar fits snugly, but is not as heavy as I had hoped. It hold a thin shower curtain very well, but would not hold up to a heavier curtain. Perfect for my use/
