Review on TICOFTECH Combination Stainless Protractor Measuring by Jose Guzman

For the price, this combo box is a good choice. It offers an angle that is very close to true 90° at full extension - close enough for most woodworking needs. It is a little tricky to attach the fastening button that fixes the rule. This is reflected in the 4 star rating, otherwise it would have been 5 stars.
