Accurate Center head, Good value fot the money.
I was impressed with the precision of this square set. I purchased it for the centering square and have not used the combination square head or the protractor head (in fact I recycled them). We use combination and centering squares frequently and have several (one for each location we need to use one). We have Starretts for precision work and where we use combination squares the most, but I don't really want to fork over that much money for places where the tools are likely to be damaged or where precision really isn't that important. This has been the first centering square that was accurate that I have ever found besides a Starrett. I can't give it 5 stars because the materials aren't that durable (the head is cast aluminum) and the workmanship on it is what you would expect for the price, but kudos for the accurate centering head which has been much harder to find than it should have been. Good value for the money.

like other posters have mentioned
like other posters have mentioned, when you remove various implements from the ruler, it's easy to lose the clamping screw. annoying, but livable. I bought it primarily for the centering square, and it proved to be plenty accurate for my home project use (mini Chinese lathe, etc.). If I were making my living making high precision parts on commercial metalworking tools, I'd by starrett, but for the money, these were perfectly suitable.

Quality was horrible, as a engineering college student i had hoped ...
Quality was horrible, as a engineering college student i had hoped for something half decent for the cost. Its worthless and has the quality of a child's toy. The edges are so rough that it wont give a true edge. I could tune it and hone it to true however the parts are so cheaply made its not even worth it. Immediately returned and will bump up at least a price range. If you think that its worth dealing with it for the price, go for it! I don't have enough time to use a defective tool.

Poor finish but accurate - but, hey, it doesn't cost an arm and a leg, either
The finish of this tool is pretty much what you'd expect at this price, but that doesn't mean that it is not good or usable. The ruler is thick stainless steel with inches on one side and millimeters on the other, cleanly and precisely etched. The heads (square, protractor and center) are aluminum. While accurate, they are not of the best finish. Mine has some small scratches on the bare edges and chips in the paint that look like they were handled roughly in the factory. The bubble levels are plastic, but in good condition and they work as they are supposed to. The protractor rule is printed on a thin piece of metal adhered to the protractor, but it is inset and should not suffer wear from normal use. The tightening post/nut for each head are spring loaded, but don't have a retainer so that when the head is disengaged from the ruler, the tightening assembly is a loose piece and the springs might be easy to lose.
Packaging is a plastic blister on cardboard. With a decent storage case, Oshlun should be able to add a few dollars to the price and make it a more satisfactory product. I imagine I will end up building or adapting a case to hold mine.
Overall the product quality is consistent with the price, and a few minor scratches and chips can be ignored since I didn't pay $50+ for it. Even though finish is not perfect, the heads and ruler are accurate and the tool will do everything it should do. If it was unusable it would have gotten a single star - as it is, 4 stars represents the usefulness of the tool relative to it's price.

Oshlun MTM-CS 12-Inch Combination Square Set
I really like the Combination Square with attachments. It is very handy to have the extras with different projects. The Stainless steel rule was a surprise because mine are not. The problem I saw after handling it was the attachments would have to be assembled each time you want to use them. Since I had two squares laying around I thought that I could use them to complete the other two attachments and I would not have to disassemble and put together each use. So it worked out very nice. A very good price at BTA-MALL and well worth buying. I got the free shipping with my total order combined. Not bad at all!

Not even close to being accurate. I should have read the reviews first.

The problem with this combination square is a design flaw. Once you remove a component (protractor, square or center finder) from the ruler the spring loaded screw just falls out. So it can easily be lost. They just need a quick redesign that allows for the screw to remain in place.
