[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]: From a woman who sold out her body ages ago and now attempts to be a partisan hack, and poorly at that. Why anyone would want to wipe their feet on this dirty carpet is beyond me. Not worth the time it took to phone in sex.
[EX A]: Negative

[EX Q]: Please do not categorize this band as they will elude any classification you attempt. That's the essence and beauty of music that's carefully woven and passionately performed.Dredg is an anomale and I pray they stay true to their pursuit and void all "commercial" temptations lured by record execs a.k.a. SATAN. Stay the course guys...!OH YEAH I FORGOT, BUY ALL THEIR CD'S AND DO WHAT MOST PEOPLE DON'T DO ANYMORE...REALLY LISTEN AND IMAGINE.
[EX A]:
Positive
