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.

The lady is kinda annoying. But the videos made me feel prepared and made me feel comfortable with my decision to not go to any formal classes, these were more than enough.

Positive

question:
If you need a grammar reference, this may well serve until you find a better one. It might be of greater utility if the tone wasn't vaguely condescending and pedantic, and it eschews the panoply of actual examples in favor of definitions. To wit: the 2nd person singular present perfect conjugation of "to love" results in "If you have been loved..." gives me one (singular) example but not the rationale of when to use this. The density of the text preceding the example conjugations will require your own self-study to master (if you must) the ability to spin off a subjunctive 3rd person plural present tense conjugation.The best recommendation I can offer for this is as a companion for language learners who need a quick reference for English analogs of other-language conjugations, such as when you try to conjugate "falar" and need to know which one to use.--#
