Good little tool for the price. Build quality is ok, a little loose but does the job. Light weight materials used may not last forever but it is cheap so you can just get another one :)

I love the size of this square, and it is reasonably accurate, the price was great, the only downfall is the locking mechanism for the rule, it does work but frequently comes loose causing you start again
Sloppy and feels cheap. Spend the extra and buy something decent first time
The combo square is so accurate than the best of them it is Light and great value .
The lock screw on the ruler is hard to lock the same as the 300mm
Perfectly adequate. It's not a precision instrument. If you want a precision instrument you need to buy something else, but its ideal for the DIY jobs around the house that need to be squared up.
The blade stays loose and gnurled nut jams when tightened.
Purchased 2 weeks ago total rubbish the locking mechanism doesn't work couldn't square up a politicians forked tongue.
