Query: What A Great Tool

...this is one amazing little tool. The Angle WIZ made my diagonal ceramic tile installation a breeze. It was simple and easy to use and made perfect measurements, I would have wasted many hours and lots of $'s on tile without it. I don't think I threw away any tile due to a bad measurement. I also found the video very helpful, I was expecting the video that came with the tool to show me how to use the Angle WIZ but was pleasantly surprized to find it shows you everything you need to know to lay tile, how to layout the room, prepare the floor, even shows you how to remove and replace the toilet properly, a must see for the novice installer. All in all I found the Angle WIZ to be one of the neatest tools I have ever purchased. Good job Amazon, this is one great tool.
