Review: First Impressions - Keep in mind, I am not a machinist or a fine wood worker. However, I routinely need to make accurate pencil-mark measurements, and nothing in my shop was cutting it. I've just received the Incra T-Rule, and I'm already happy with the purchase. I've spot-checked the measurements with calipers, and they're very accurate. The right angle may not be perfect, but it's certainly better than any of the other four squaring devices I own. I have no question this will work well for my purposes. That being said, consumers should know, this is not the all-singing-all-dancing second coming of measuring devices. Here are some limitations worth noting: * If you are looking straight at the ruler, it is nice and rigid along the x and y axises. However, it very flexible along the z axis. This can be a benefit under the right circumstances, and won't be an issue on relatively flat boards. Still, if you require a stiff ruler throughout, shop elsewhere. Furthermore, be prepared to treat and store this device a bit delicately. * Down to 1/32" measurements should be fine, but 1/64 accuracy, although featured on the ruler, likely will not work well. At this fine a measure, a spec of dust or the pencil could throw off the measurement. If you consistently need to measure at this level of precision, you might need to spend money on some Swiss precision stuff. * Although a great right angle, Incra makes no claims as to how good a right angle it is. So, probably best not to think of this as a perfect square. * The writing is, by necessity, very small. If you need reading glasses, you'll need them now. * You can only make tick marks with a 5mm mechanical pencil. Not much of anything else will work. So, if you don't have one, get one. * This device will make better measurements - not faster ones. It's still best to move slowly and measure twice. Still, a great product. It'll do what it promises.
Review: Accurate, Easy to Use, and Worth It - I am really impressed with the T6 inch version. It was easy to figure out right away and feels very smooth to use. The accuracy is excellent and I can trust the results every time. It is lightweight, comfortable in the hand, and has quickly become one of my favorite tools. I honestly love this thing and would recommend it to anyone looking for something reliable and easy to use.

### ⭐⭐⭐⭐⭐ Perfect - if you understand what it's for.
*by D***M on March 26, 2024*

Ordered the INCRA T-RULE06 6-Inch and the INCRA TINYT03 3-inch precision T-rule and am very impressed with both INCRA products. The precision and costruction are superb. My only request would be the inclusion of a rigid storage case. These are not something you just toss into your toolbox. But with proper care, they will last a long time. Most of the complaints I've read seem to center around the "tiny holes" and "flimsy" material. Both are necessary to preserve the precision of the instrument. You just can't accurately mark a 1/32nd increment using a standard #2 lead pencil thru a deep hole. Using a (required) 0.5 mm mechanical pencil, you can mark 2 lines 1/32nd apart and still see them as individual lines! This is incredibly difficult using a standard pencil no matter how "sharp" it is. Out of curiosity, I measured the thickness of the ruler at 0.010" using a Starrett micrometer. The ruler will never lie "perfectly flat" on its own, and it doesn't matter! In use, your fingers and the pencil will easily keep it "flat" against the work surface. Another common compaint seems to be the small writing on the ruler. There is a LOT of information being presented on the ruler, and it is very clearly ENGRAVED. Yes, it's small, and I must use my reading glasses to insert the pencil into the correct hole. But the text is all necessary and probably as big as it can be and still fit in the available space. I'm getting to be a bit old, so I don't blame the instrument - I blame my eyes. Being an "intermediate" level woodworker, my skills don't yet allow me to work to the level of precision possible with this instrument. With this ruler, I can now mark 2 perfectly parallel lines at a precise location. But for me, actually making an accurate cut along those lines - well, I'm still working on that! Overall, I'm quite impressed with the Incra T-rules and would definitely buy them again.
