This is not a typical Adam Sandler movie, which is not necessarily a bad thing, but it kind of is here. First of all it's not funny. It's about "comedy" but I wouldn't consider the movie itself to be a comedy, although there are a few funny things in it I suppose. This movie seems like it's all over the place. It has a long runtime but it doesnt really accomplish much. Some people might like the story, but it was pretty dull to me.

Ex Output:
Negative

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.
