Great Value and Functionality For The Price
Size: 7-1/4-inch Style: MACH-1 with Level Vial
The markings are easy to read, with a lot of different functions, so it's quite versatile. The level is particularly nice to have built in. It appears to be good quality, but I suspect the paint (or powder coat?) will start to show wear with hard use. So I'm being careful with it, using it primarily at my sheet metal brake and using my trusty Swanson for rough carpentry and field work where it gets beaten up since it's markings are cast in. Overall I'm very pleased with it, especially for the price. ... show more

Love it. Very accurate (checked versus Starrett carpenter square and various angle gauges). I prefer white on black labeling over my Swanson speed square (little level is nice in a pinch too). Tons of markings for almost any situation.

Dead accurate all around
Size: 7-1/4-inch Style: MACH-1 with Level Vial
Tested 90 and 45 with my machinist squares and tested the bubble against my stabilas and it's dead nuts all around. It is aluminum though so I've already dented a couple corners from drops. Still worth every penny compared to the competition that costs 2-5x. Still need to keep a couple swanson pro squares around for deck spacing. ... show more

Great value
Size: 7-1/4-inch Style: MACH-1 with Level Vial
Very legible, multiple functions and a lot of cheat sheets squeezed onto this thing. It is basically the ultimate square. Especially at the price point. I only returned it in exchange for a squijig cause I like the ability to change the level heel with a 3/16 heel depending on what I do.

Best speed square
Size: 7-1/4-inch Style: MACH-1 with Level Vial
This thing is awesome. All the scribe marks on it being able to not only do quarter inch increments but also 1/8 inch increments is a game changer I mean I'm constantly using that feature. Plus the level I don't have to carry a torpedo around. And all the other features like inch and a half marks 3 inch marks etc make this super nice speed square to use ... show more
