Input: Consider Input: 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.

Output: Negative

Input: Consider Input: I purchased this player over 4 months ago. I read all of the reviews and I was aware of the pros and cons going in. This player is slightly thicker than the same capacity ipod. On the upside, the battery is user upgradeable, which iPod users can't do. The main downside to this player is the software. I highly recommend NotMad Explorer from http://www.redchairsoftware.com as a replacement for the poor Creative software. The upsides are great sound quality, great capacity, decent battery life and a good price. If you don't care about looking trendy carrying an iPod, take a good hard look at the Creative Nomad Zen players.


Output: Positive
