⭐⭐⭐⭐⭐ Emily Tran - High School Student
"I bought this compass set for my geometry class last semester and it’s been a game-changer. The zinc alloy compass holds its shape perfectly—no wobbling when drawing circles, unlike the flimsy plastic ones from before. The transparent case makes it easy to find the ruler or protractor fast during tests. I also love that it has both metric and imperial markings. After 5 months of daily use, everything still looks brand new."Purchase Date: September 2024 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Daniel Park - Civil Engineering Intern
"I grabbed the Advanced Model of this set for my internship, and it’s held up better than expected. I use it for sketching site layouts and checking angles on blueprints. The divider is precise, and the reinforced ruler hasn’t warped despite being tossed in my backpack every day. The clear case is surprisingly useful—I can see exactly which tool I need without unzipping. For a student-grade product, the build quality feels professional. Worth every penny."Purchase Date: February 2025 | Usage Period: 3 months
⭐⭐⭐⭐☆ Maya Johnson - Art Academy Student
"I mainly use this for technical drawing and perspective work. The compass is sturdier than anything I’ve used at school, and the dual-scale ruler helps when switching between project requirements. My only reason for not giving 5 stars is that the eraser wears down quickly with heavy use. But overall, the portability and organization of the transparent case make it ideal for carrying between classes. I even added a spare pencil and small stencil—fits perfectly!"Purchase Date: November 2024 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Ms. Rebecca Liu - Middle School Math Teacher
"As a teacher, I buy a lot of classroom supplies, and this is one of the best investments I’ve made. I purchased 15 sets for our math lab, and the EN71 certification gave me peace of mind for student safety. The zinc alloy tools resist bending, even with rough handling, and the clear cases help students stay organized. I’ve noticed fewer lost components compared to older kits. Students can quickly spot the protractor or compass they need—saving time during lessons. Highly recommend for any educator."Purchase Date: January 2025 | Usage Period: 4 months
⭐⭐⭐⭐⭐ Carlos Mendez - Surveying Technician
"I work outdoors a lot and needed a reliable, portable drafting kit. The Pro Model with the military-grade resin case is rugged as promised. I’ve used it in humid conditions and even dropped it once—no damage. The zinc alloy divider hasn’t corroded, and the lightweight design makes it easy to carry in my field pack. It’s not a full drafting table, but for quick sketches and measurements on-site, it’s spot-on. Great for engineers or architects who work in the field."Purchase Date: April 2025 | Usage Period: 1 month
Average Rating: 4.9/5 ⭐ (89 Reviews)
Dr. Alan Foster - STEM Education Consultant
"After evaluating over 30 geometry tool sets, I consistently recommend this compass set for middle and high school programs. The combination of zinc alloy durability, dual-scale measurement tools, and EN71 safety certification makes it ideal for classroom use. Its transparent storage system also supports independent learning by reducing setup time."
Lena Schmidt - Product Design Engineer
"For a compact drafting solution, this set strikes the right balance between portability and precision. The weight distribution of the metal compass improves control, and the modular customization options allow professionals to adapt it for specialized tasks. A rare example of a student-focused product with professional-grade features."
