Question: About four weeks ago, I purchased at a Home Depot in Florida the Plasplugs "Master Tiler", model number: DWW180US-BX.I am using it for a porcelain tile installation. The original blade worked ok for the initial cuts, but I need to replace it for the proper blade type for the tile. I had bought a porcelain tile replacement blade from a blade mfr when I bought the saw. When I got around to replacing the blade, I found out that the Plasplugs machine uses a different "arbor" than everybody else. The replacement blade was worthless to me.I then called the Plasplugs US office to order the "high glaze" blade. Much to my chagrin, I was told the "all blades except the standard have been discontinued".I just bought this saw four weeks ago! I think it is very irresponsible for a manufacturer to behave in this matter.You can be assured that I will avoid any Plasplug product in the future.

Question: I have never been so disgusted (or sickenly entertained) by a movie before. I am one of the few who have ACTUALLY read the ODYSSEY. I did like the poem. After reading it, I decided to watch the movie. There were almost NO accurate allusions at all to the poem. The characters' acting skills were that of an elementary school kids, and the scenes were obviously fake. I feel bad for Homer, he must be spinning in his grave. The fact that got 4 out of 5 stars is most appalling. I feel sorry for humanity as it is, believing such [nonsense] is the work of Homer.

Answer:
Negative
