Review on π Accurate and Durable: Helix Plastic T-Square Inch 20002 β Perfect for Precise Measurements and Drawing by Philip Davenport
The straight edge is not straight.
The edges of the ruler are not smooth. There are small bumps and pits along the edge. If you used it to draw straight lines it wouldn't work. What does a T-shaped square with a jagged edge mean?
Pros
- Sturdy construction
Cons
- I have no particular complaints about it, everything is fine
