Fancy magnetic power
Size: 12-Inch
This product is really awesome. The magnets are strong enough to keep it in place and it's not that hard to slide it when needed as well. The little scribe they added into it was a nice touch as well. I haven't used it a whole lot yet, but it seems very accurate and well built.

Great handy square
Size: 12-Inch
Really nice for quick square check and just pull out the ruler easily when just need ruler. Liked enough to purchase one for friend doing wood work. Checked the square and it was right on

Don't like the ruler
Size: 12-Inch
It seems like a left handed ruler to me. Held in the left hand the inch is upside down and counting backwards. Held in the right hand the inch is ok but I mark with right hand, which is holding the square. I wish they made this inch only and readable left or right. I do like the magnet. Would not buy again with this ruler. EDIT: I've looked around and it looks like this is on all rulers which are both inch/metric. I'll keep searching for an imperial only ruler. When held in left hand I want 1" to be on the right (both scales). When held in right hand I want 1" to be on the left (both scales). I have several like this but they only go to 16th inch. ... show more

GREAT IDEA & WORKS GREAT!
Size: 12-Inch
THE BLADE DOES NOT WIGGLE-SLIDE AROUND LOOSE OR FALL OFF! RARE EARTH MAGNETS WORK GREAT, I CAN EVEN USE MY OTHER 6 OR 18 INCH STEEL COMBINATION SQUARE BLADES IN THIS TOOL, THEY JUST SLIDE RIGHT INTO THE SLOT AND ATTACH THEMSELVES FIRMLY AGAINST THE BANK OF MAGNETS. YOU MUST SLIDE/PULL THE BLADE TO MAKE ADJUSTMENTS: FINE ADJUSTMENT ARE EASILY "PUSHED" INTO PLACE AND IT HOLDS TIGHT WITH NO SLOP! I CHECKED THE SQUARENESS OF THE 12 INCH BLADE AT 90 DEGREES WITH MY DIGITAL PROTRACTOR AND IT WAS: 90.1 DEGREES WHICH IS ACCURATE FOR MOST CONSTRUCTION NEEDS. I REALLY LIKE NOT HAVING TO WORRY ABOUT BRASS KNOBS COMING LOOSE OR NOT TIGHTENING WELL, AND THE INCLUDED SCRATCH PIN WILL NOT FALL OFF EITHER! NOW THIS IS WORTH THE WAIT TO RECEIVE IN THE MAIL! ... show more

Great idea...just needs very easy tweak to be perfect.
Size: 12-Inch
A few reviewers mentioned that this "square" is not square. That was true for mine as well, but I investigated it further and determined the problem was NOT with the metal, but rather the PAINT. When they put the red paint on it, it seems to get sprayed on the important part of the "handle" right where the rule sits. Moreover, the pain was only on one side and not the other. That made for a very small imperfection in the squareness. I took a utility knife and scraped the glob of paint off where the rule rests on the handle, and re-checked the squareness...now perfect. This is a great design and I find it to be very easy to use and now very accurate. Also VERY easy to pull the ruler out and use it by itself and then pop it back in. ... show more

Square frame, un-square ruler

The magnetic tension on this is fantastic... It's very strong without being overly difficult to adjust, and absolutely zero play in any direction. The body of the combo square also appeared to have appropriately-flat edges when compared to one of my Woodpeckers tools. However, the ruler itself is drastically out of sorts, as one end is much wider than the other, and the edge of the ruler itself is anything but square. This unfortunately makes the whole thing useless, but if you can find a trustworthy ferrous ruler to fill its place then it can still be a good, unique combo square. It's really too bad, too, because the markings on the ruler are really nice and clear (better than my Woodpeckers), and accurate. The first two images are from opposite ends of the ruler, and the next two images are those ends compared to the Woodpeckers ruler (it should be clear which one is which). Unfortunately, the Woodpeckers ruler isn't attracted to the magnets, so now the search for a ferrous precision ruler begins. ... show more
