Fantastic square.
Fantastic speed square. Has all the marked measurements needed and the built in level is handy to have. This square is built right and heavy duty. Highly recommended if you’re a carpenter looking for a new one.

Well made
Well made, easy to read. I'm not using the bubble level near as much as I thought I would, but still handy for simple checks.

The t I t s
It's everything a speed square can be. It will not fit into the holstery speed square holster because the foot is too thicc because of the bubble. The bubble is replaceable but good luck finding one. There are a few Johnson brand ones here in the way way back of Amazon, if you can make it down the rabbit hole, but the sizes are inconveniently advertised as fractions that don't quite translate to 16ths of an inch. You would have to remove the bubble and then use a caliper, which I don't have. I'm worried about it being stolen at work because there's nowhere on the damn thing I can paint pen my name on it. It's almost too many functions and I'm probably never going to use them all.

Awesome
I’m actually really impressed i have More expensive squares, including a trig jig I just hung on the shelf after getting this. This thing has a lot more markings on it and options than the others, and the level seems to be more accurate.. I’m 55 done construction the last 40 years

Sehr guter Begleiter beim Handwerken! Habe Ihn gekauft, da ich nicht mehr mit diesen "weichen Stahl/Blechlinealen" der Schreinerwinkel arbeiten wollte. Ein sehr vielseitiges und stabiles Werkzeug in einer einfachen Form. Diese Größe passt gut in meinen Werkzeuggürtel. Der Kauf war für mich ein voller Erfolg! P.S. Wenn der Hersteller noch eine Libelle einarbeiten könnte/würde ohne die Form zu verändern wäre das ein Traum...

White writing on black stands out well. Better than my old silver natural aluminium colour. Metric is a bonus now.

Very good. I am just afraid the markings fade after a while being used.

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 .
