Clearly one of the best small squares out there
Super handy size of this square makes it a must have around the wood shop. Love the white on black easy-read markings. The price is right and it seems to be a quality tool. Was going to pay the price for one of those fancy smaller squares, but glad I didn't. For what I would have paid, I could have three of these. Will definitely get another one to have as a spare.

Nice product, grippy texture that doesn't scratch painted metals
I like these small squares, I moved over to this square from the Milwaukee version and so far I like it. This square has a grippy coating that doesn't scratch up downspouts I mainly use it for marking cuts while building 2x3 steel downspouts. It's very comfortable over using the regular speed square.

Bought this as needed a small square to carry on me at all times for work. Shipping from the USA to Australia arrived 2 weeks earlier then Amazon stayed with I have found with my other purchases which is great. Handy little sturdy square . Better quality then the Bunnings brands . Would recommend . Only negative is the built in note pad wich doesn’t erase easily. It’s just a cute little gimmick but as I don’t use the note pad

UNA ESCUADRA CON MEDIO AGÜJERO AL FINAL? VAYA ESCUADRA, NO SALEN LAS RECTAS BIEN, SALEN CON UNA CURVITA PEQUEÑA AL FINAL QUE TIENES QUE RECTIFICAR A CADA MOMENTO QUE LA USAS, MOLESTA Y PIERDES TIEMPO .

I had previously purchased a cheaper alternative - big mistake. Bought this unit and it is so much better, build quality, accuracy and features. Don't waste your money on cheap alternatives- buy quality and buy it right first time. I would recommend this product to any woodworking enthusiast.
