Products does not meet required need. Wrong measurements.

Nice triangle rulers that work as expected. They are rulers after all, no rocket science. But you could use them for rocket science because they are metric, so it is a good purchase.

Bought for school. They do the job

Just right not too big or small.

Me llego toda quebrada la escuadra.

There seems to be a bit of confusion about these squares in some of the other reviews: they're inch scale squares with 1/10th inch sub-divisions. That makes them very useful for people who work with 10x10 division imperial graph paper, or who use an engineer's scale for drafting, which is also based on 10ths rather than power of 2 divisions. If this is what you're looking for, I think you'll be very happy. For those who wanted something else, I don't know what to tell you: the listing when I purchased made it clear enough what they were. The squares themselves have good optical clarity. I've put them up against my precision rules, and the linear length markings seem to be quite accurate. I don't have a precision protractor to compare the angle measures to, but the angle marks look quite regularly spaced to my eye. A benefit of the transparent plastic is the inclusion of 1/2" and 1" offset lines off the edge, which I find highly useful. I also like that both linear scales converge exactly at the corner. For some reason that is mystifying to me, many squares have the scale stop slightly short of the corner, but maybe there's a use case for that design which I'm unaware of.
