Toolzilla 7-Inch Aluminum Miter Saw Protractor Angle Finder - Measuring Tool with Multiple Scales Features for Woodworking Metalworking and All Building Trade

I got a brand name one 4 times the price and lost it. Ordered this one and one that was double the price of this and all three brands are Identical tools with different labels. Really this one I was happy because it came with a cloth carry bag and the others didn't.

In my particular instance at least, the protractor appears accurate. Comparable 'value line' protractors are generally plastic; this is all aluminium and supplied with a handy storage pouch. However, similarly in my instance, the tool did make and awful screeching sound when rotated which transpired to be due to an unlubricated friction 'O-ring' internally. Applying a very light smear of oil eliminated this (having removed hex screw). Overall, good for the money.

Prima tool

Stelle ich auf der eine Skala 45 Grad ein sollte auf der außeren Skala auch exakt 90 Grad stehen. Steht aber auf 91 Grad. Sieht man auch auf der Bildern in der Beschreibung. Habe mir eine Version direkt aus China bestellt, da stimmt die Skala und sie hat 1/3 gekostet.

As you will see from the picture the scale out by 2 degrees which makes using this a massive pain. Spent all night trying to understand why I was getting odd / wrong / poor angles but 0 degrees isn’t 0 on the other scale.
