Alvin, Geometry Set, High Tech Set Model - Set of 4

I bought this set for my child to use in school. All we really needed was the protractor, but the triangles work as great straight edges in place geometry. I like the clear design of the protractor. I only wish the lines indicating degrees were also on the inside of the arc. The plastic is a decent quality. The lines are all easy and clear to read.

Not so great. I really try to buy Alvin for these type of products but this kit is super cheaply made and arrived bent. I'm trying to heat it to straighten it out but won't be updating the review because I shouldn't have to do anything to use them as designed.

Bought this for my wife. She uses them for her art projects and seems satisfied.

I got this kit for my son to use daily at school. so far, he loves it and uses it everyday.
