[EX 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.
[EX A]: Positive

[EX Q]: Bought this set based on low price and good reviews. Works fine for poking logs occasionally and cleaning up when stove is cold, but while using the shovel in the fire, the black coating started bubbling, then caught fire.
[EX A]: Negative

[EX Q]: Halliday's excellent introduction makes a historical survey of Shakespeare criticism . Halliday claims that new perceptions of Shakespeare were developed at fifty year intervals starting with his his contemporaries, then with Dryden in the Restoration, Pope in the Augustan Age, Johnson in the Age of Reason, and Coleridge in the Romantic Age. One of the surprising revelations is that it is only with Coleridge that Shakespeare is written and thought about primarily as a poet. It is Coleridge who too lays waste the conception that Shakespeare was a wild , careless genius with little concern for the artistic construction of his work.The second part of the work contains brief selections of criticisms about the individual plays.I found this work provides a sense of the overall development of Shakespeare criticism from its inception to the mid- twentieth century.A valuable work.
[EX A]:
Positive
