Review on GEOMA Contour Gauge Shape Duplicator with Metal Lock 10-Inch - Accurately Replicate Irregular Shapes - Versatile Measuring Profile Tool - Ideal Christmas Gift for Handyman, Woodworking, Carpentry, Flooring, and DIY Projects by Jay Koterba

A+ Highly recommended. This tool came in handy when we started laying new tiles for our kitchen renovation. We had some really tricky corners that we needed to cut and this tool made it easy to copy the profile onto the tiles. I did some research before deciding on the Geoma contour sensor. Many of the ones I found were made without the locking and clamping features that the Geoma product offered. Many other manufacturers also offer a smaller device with a 10" device. In my experience, you will always use a larger device. At least for the work I've done, I've never stopped saying I wish I could would have a smaller device.I highly recommend this tool to anyone who should have it in their toolbox.
