  • Great rulers for the price!
Great rulers for the price! Easy to read, accurate and strong. The quality for the price is really good! I use these a lot for suspension settings on MTB and MX bikes, love them!

  • High quality and easy to ready
It's nice to see quality products like this. Too many are cheaply made but this set is excellent. Very high quality, easy to read, highly accurate.

  • Handy multipack of Machinist Rulers
I found this pack when I was doing work on 3d printers. It is amazing all the places I need to take measurements and having the different lengths means I always have the right size. They are sturdy enough not to flex, easy to read and inexpensive while being of decent quality.

  • Nice thin markings, easy to be precise
Note that the largest ruler does come with a sleeve just like the others; I just lost it. These four rulers are nice, made from stainless steel. The edges are sharp enough to slice you, which is good for accurately tracing lines. They come in two lengths and two widths. All measurements are in millimeters: The first is 355.50 long, 26.25±0.05 wide, 0.91±0.02 thick. The second is 304.50 long, 26.20±0.05 wide, 0.91±0.01 thick. The third is 203.00 long, 19.37±0.01 wide, 0.90±0.01 thick. The fourth is 152.00 long, 19.16±0.01 wide 0.90±0.01 thick. All measurements are approximate. All of them appear to be almost perfectly flat (which is impressive), and straight on the business edge. The markings are thin enough that you don't lose accuracy, and it is easy to precisely measure up to 500 microns. Even further, I found it easy to eyeball accurately down to 100 microns because the lines are so thin, straight and sharp. I also like the font. One issue you may note is that the ends are a cut a little bit rough. They have a slight bevel where a guillotine severed the length. Additionally, they do not appear to be perfectly perpendicular with the longest edges, and have a slight variance. This variance means that if you're trying to measure from the zero-end, your measurements will be off slightly. I have a picture attached with the markings lined up which illustrates this issue. It is more noticeable from the imperial side on the 300mm long ruler, which means that particular ruler has a slight offset on that specific side. As for the orange and transparent sleeves that they come with, I have a complaint. These are almost not worth keeping, but only almost. You can't hang them by a nail through the hole because the cut is on the wrong end (gravity), and this makes me wonder why the hole is there in the first place. The tops are also heat-sealed, which means that you can't remedy the problem by sealing the bottom and opening the top. I understand that these sleeves are almost definitively just for protecting the markings and brush texture during transit, and they are still useful for this purpose. Nevertheless, the material is thin and the design cuts prevent them from being more useful. It would have also been nice if cardboard outer-sleeve were more durable, as I would like to keep them in this. There is no easy way to open the package without ripping this packaging. All in all, great rulers for the price. Regardless of my complaints, this is still a 5/5 star item. ... show more

  • Very accurate
I consider these rulers to be pretty accurate for two reasons: 1) They coincide with my mini caliper. 2) The rulers accurately measure the width of an NVMe flash hard drive to 22mm. An NVMe hard drive is typically 22mm in width. As shown in the photos you see the ruler show exactly 22mm for the width of the NVMe hard drive. This is why you may see NVMe hard drives listed as 2280. It means 22 mm in width and 80mm in length. You'll also see in the inch units that the ruler measures the width of the NVMe hard drive as 28/32" or 7/8" as a reduced fraction which is 22.23mm. It seems my mini caliper might be off by ~ .2mm if I consider the NVMe drive to be exactly 22mm in width. The two things I don't like about these rulers are that they were slightly bent and that they are made in China and not the U.S. Other than that they are pretty good rulers and I recommend them for 1mm resolution measuring. ... show more

  • Good for the price
Seem to be good quality, and accurate. Handy to have in the shop.

  • Accurate enough
OK Folks I've read many reviews stating the edges were sharp & the ends were not dead nuts accurate in the end grind. I purchased three sets thinking at least one set would be accurate. I found all the end grinds to be within a 64th or better. The edges were somewhat sharp but not enough to slice a finger. Could be I got lucky with a few exceptional sets. For the price point they can't be beat. You'll not find a better deal anywhere for a four piece set of stainless rules. ... show more
