Rated 3.9 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by Great little tool I also wanted to measure my rotors and this little guy did the trick. This device is much smaller than others I had looked at which cost $40 and up. If I had bought any of the larger ones I would have had to take them back due to the tight space between the rotor and brake shield. It doesn't say this in the specs but its max measuring width is 1 inch. One thing to watch out for is not to wipe off the lubricant that's on the barrel. I mistakenly thought I was cleaning it off but that was not the case so I had to re-lube it. The car I have is BMW 328xi E92, so yes it will work for you if you also have an E9x body style. My brake shield got in the way, but I was able to flex it back just enough to get the micrometer in there, without permanently bending the shield. October 3, 2011
Rated 4.0 out of 5.0 by Does exactly what I need it to do. Needed to verify paper thickness, does what I expected at a much better price than anticapated. October 12, 2012
Rated 4.0 out of 5.0 by Hard to find, good price on standard micrometer Needed another micrometer, as I have two tool boxes. Finding it for under $16 made the option of having 2 affordable. The local T__V___ hardware store is twice that price. The micrometer is fairly well made, and measures to 1/1000", which is what I need to measure thicknesses of sheet metal and hobby wood-- as well as golf club shaft diameters. It is easy to use, and of solid construction. When this one arrived, it appears it was knocked out of calibration, and I had to recalibrate it-- or zero the device. I think that problem is behind me, but I dinged the quality 2* because of this. Other than that, I received the item well within the expected timeframe, received both texts and emails, and picked the item up the following Monday morning. The clerk was on the ball, and found it right away, the entire process took about 2 minutes. Monday morning is a good time to pick up items there. That is also good. November 4, 2014
Rated 1.0 out of 5.0 by Unsatisfactory in all respects I have many tools made by General. Most are pretty good. Not so with this micrometer. For something that is supposed to be a precision instrument, it is un-usable. I have good tools from General that are made in the U.S. For this micrometer, they went to the lowest production standards, farmed it out to the far east, and ended up with a dud. The spindle thread is so rough there is no way to get a good measurement, and the thimble click sticks. I sent it back for a refund. Don't waste your money. After years of using General Tools, I'm done with them. March 20, 2012
Rated 4.0 out of 5.0 by competent processing and delivery The micrometer is as advertised unlike my recent tool rental February 12, 2015
Rated 4.0 out of 5.0 by Interesting product! This device is for the most part used in the textile, tile, forest, construction and science fields. It is typically used by professionals. I had a dispute about the depth of some acrylic panels that I bought (not from Homedepot). I was told by the manufacturer that I needed a micrometer that is used by the industry and not a typical ruler to measure the true depth . I learned how to used a new instrument, so I'm happy!

Rated 5.0 out of 5.0 by Way better than I expected! My Brown & Sharp and Lukin tools went "away" when I retired and sold my shop. As a hobby now, I reload ammunition (bullets) and needed to make very precise measurements of bullets, prior (and after) reloading. A 38 special revolver uses bullets .358 in diameter, A 9mm uses .356 diameter bullets. How else would I know, which one to use? This micrometer works excellent! I am DEFINITELY a happy customer!

Rated 3.0 out of 5.0 by Confusing. A good tool for the price if you know how to use a micrometer in advance because the instructions were somewhat unhelpful. They did not match the tool. For instance, each graduation line on the thimble equals .0005" rather than the stated .001". The picture of the graduation lines also did not match the tool. Honestly, I would rather pay more for an American made tool with proper instructions. March 23, 2011
