Q: I'm no great fan of bluegrass or country, but this release intrigued me because - like many people, I suspect - I have a soft spot for Dolly. "The Grass is Blue", though, really is as good as the other reviewers have said.

A: Positive

Q: I was looking for a shower door that could open from either the left or the right and I did not want one to choose for me. This door ticks and fits all the right boxes in that department. I like the crystal glass effect too. It is very clear and allows a lot of light into the shower hub. It is frameless too which is what was asked for by the wife.Its sturdy quarter of an inch thick glass also is a nice feature. But most of all the pivot door is a feature I got on with too.

A: Positive

Q: You could not pick a more annoying instructor than Sheir Bayles. She absolutely ruins this class. The video quality is horrible as are the 80's rejects posing as her audience. My wife (a physician) and I cringed through the entire presentation.If you buy this video after reading my review, you deserve to lose your money AND be subjected to Sheri Bayles for over 5 grueling hours.

A:
Negative
