Multi-Functional 300mm Combination Square 45/90 Degree Square Angle Ruler Measuring Tools with Bubble Level

Doesn't accurately show 90 or 45 degrees. Principal culprit is the ruler, which has a variety of distances between edge and center groove. One side/end shows 10.96mm and the other 11.32mm so good luck expecting accuracy. As the aluminium block and spirit level are basically accurate I am tempted to fix the ruler and keep it. The screw tightener is passable but I think I will make a tighter fitting one, which wouldn't be hard. I can't generally recommend. You have to either learn to fix these cheapies or splash money on a Starrett.

I got this for a shelving project that I was building and it seems accurate and sturdy enough for the job, possibly not the best quality available but very good for the price and got the job done

Bought this to replace a previous tool that was over 30 years of age and had got to the end of its useful life.

Checked against two other squares and consistently out of true by small but sometimes significant amount.I may use rule component as measures were accurately although steel rule was bowed as delivered. Also one I received not reliable as a true square although probably OK for general work but I wished to use it also to set up band and table saw for which a 0.5 -1mm out may be too much.

Does the job needed. And with a scribe attached. In case you cant find a pencil. With sliding angle and ruler it's great for measuring cuts to work easily.

Thank you.

It does everything I expected it to dp

Great
