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.
Positive

The book I downloaded on my Nook and Kindle doesnt seem like the same one I read in school. This version Bored me to tears.
Negative

This book was very disapointing, and misleading. Like for example wing chun has no high kicks but you will see one in this book. enough said
