Contour Gauge Duplicators, Simple Shape Contour Gauge Duplication, Instant Template For Curved and Odd Shapes, Easy Master Outline Gauge Tool for Cutting Set of 2 (5" Widen and 10" Widen)

Ok. Brought these to do a hallway. Well, that is for my son to do it....For simple shapes they are great. But for more complex they can create a problem. This is mainly down to the fact the red bits that makes the ‘shape’ you need, are too short. So they do not get into complex spaces very well. However, they are still very useful to have. And we will be watching more YouTube vids to see if there is a way to improve the problem.The lock is fantastic. I can use them to make a shape, then hold it upside down and it doesn’t budge. I know another review said they move, so maybe they had a dud one or there was a faulty batch? I got two for the price of £23. A larger red one, and a small blue one. Both hold shape and can be turned upside down and don’t move. Hopefully this is not because they are new! And the stiffness stays stiff!I do recommend because they are useful. But do be aware, with complex shapes, there could be a problem.

I bought this because of the very high reviews and comments. I must be missing something because personally I think this is absolute trash...... No lock so profile easily moves and very flimsy... I’m no novice and do lots of joinery , welding car mechanics so not exactly totally stupid. Now it’s in upcycle box to turn it into something useful......

Used for boxing in around pipework, a fantastic tool makes awkward cuts much simpler, only thing I would say is it could do with a locking mechanism to fix the slots in the irregular shape, while it didn't slide I felt it would if I wasn't holding the central section in place.

Poor quality, no clamp and too stiff to get accurate profile, inconsistent tension.

This gadget is wonderful for flooring, tiling, paper hanging etc. It works well but would be better with a lock on the unit so that it held its shape better. Colours are not to my taste, but then, its a tool and not an ornament. Yes - I recommend this. I bought the 2 together as a bundle and found the larger one of more use.
