Customers say
Customers find the contour gauge works well for their purposes, is precise, and offers good value for money. The build quality receives mixed feedback – while some say it’s well-made, others note that the metal pins can bend easily. Customers disagree on the ease of use, with some finding it easy to use while others describe it as extremely hard to work with. The fit and pin safety aspects are problematic, with customers reporting that the pins fall out and the metal rods slide too far.

Awesomely wonderful
This contour gauge is everything I hoped it would be. It creates a near-perfect replica of the shape you need. We recently remodeled several rooms and this tool did a GREAT job of getting the duplicate outline we needed to cut tile “just right.” The metal rods are tight but not too tight. In my opinion, that’s good, because they hold their shape better when you’re tracing your outline. The key to success for me seemed to be to work it slowly. You’ll see videos promoting similar products in which the user is pressing it quickly onto the shape needed. I found it worked beautifully if I took it just a tad slower.Side note: Because these metal rods can get bent if the tool is tossed about or thrown in a tool bucket, I strongly recommend storing it safely. (Ours now has its own place in my tool drawers.)Bottom line, the pricepoint is excellent, and so is the tool. Definitely five stars.

Pleasantly surprised. Works OK
I wanted a metal one, as this is, because of the much finer resolution. I was concerned that it might not work well, because of all the negative reviews. Well, it is a bit fragile, it isn’t easily adjustable if at all, and it’s a little bit stiff, but it works fine.My recommendation is to baby this thing. I’ll probably make a box for it. It’s not going to stand up to rough use, and if it falls apart I can see it being miserable to try to get back together. But again, it works.My use for it? To get contours for various wood trim things or obstacles when replacing trim or making moldings. For that it should be perfect.

GOOD AS PRICIER GUAGES
I can’t figure out why people don’t like this tool. It works exactly as it should. I have owned several of these over the years. I have bought some expensive ones and this product worked the same as the pricey ones did. This is a delicate tool. You have to be careful to keep the pins from bunching up. As for the comment from the person who said the pins were in too tightly…obviously, if they were looser, they would fall out. Also, it is important that they stay exactly in the same position without moving when you finish taking your measurements.

I struggled with this reivew
The tool appears pretty well built, not with cheap pins and ridiculously fragile plastic casing. My problem, and the reason for the three stars, is that the whole purpose of this tool is to be able to easily copy a form from one medium to another, but the pins on this tool are SO TIGHT that you have to apply a lot of force to get them to move into shape. If you’re copying sheet metal siding for, say, auto body work or using it to match grind patterns in concrete, that’s probably fine. But if you’re using it to copy shapes in more delicate material, you have to push so danged hard to move the pins into place that you run the risk of marring the source material with pin holes or even pushing the source material out of shape so you don’t get a true copy. I sprayed silicone spray on the pins and that helped some, but they’re still far too tight. If I had to guess (I intend to test this but haven’t yet), I’d have to say it takes a good ten pounds of pressure to push the pins into shape, and that’s waaaay too much for a tool of this kind.

Pretty cool
I am by no means a carpenter. This tool is priceless for those hard to calculate contour cuts. The pins are solid enough that they stay in place so that you can move from your measurement to your drawing board or work table without fear of losing the design. It has measurements marked on it which is an added bonus. This is a must have tool for the DYI people out there.

Pins can fall out or be missing
You can get a “good one or bad one” with anything. Well, I got a bad one. I took it out of the package without really looking at it. The pins were all over the place. After I tightly slid the pins together, I was missing 1” of pins! So this should be advertised as a 5” Contour Guide, not 6” Lol If the pins are stacked tightly, they stay in place. If there is any space between the pins, they literally will fall out when you tilt it vertically. There are a lot of reviews about the pins falling out. This states there are 35 pins per inch. The reason they may be falling out is the lack of pins per inch. I counted these and if the pins stacked tightly together, mine has 32 pins per inch. According to the product description, there should be 35 pins per inch. Not enough pins will result in them falling out. It’s a quality control issue. They could have at least shipped mine with all the pins!
