⭐⭐⭐⭐⭐ Ms. Emily Tran - High School Science Teacher
"I've been using the JOYUSING A3 Mini Document Camera in my biology classes since January 2025, and it’s transformed how I teach. The 13MP 4K resolution makes it easy for students in the back to see lab specimens and textbook diagrams clearly. The adjustable arm lets me zoom in on dissections in real time, and the A3 scan size fits full worksheets without repositioning. Setup takes under a minute thanks to the intuitive controls."Purchase Date: January 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ David Park - Corporate Learning & Development Manager
"We use the Pro Model with Wi-Fi for hybrid training sessions, and it’s been a game-changer. Presenting physical documents or product prototypes to remote teams is now seamless—no more scanning and uploading. The 4K 30fps streaming is smooth, and the metal chassis feels rugged enough for daily use across multiple conference rooms. Worth every penny for enterprise use."Purchase Date: November 2024 | Usage Period: 8 months
⭐⭐⭐⭐☆ Jessica Liu - Homeschooling Parent
"As a mom teaching two kids at home, this document camera has made lessons more engaging. I love how I can prop up a workbook or a science experiment and project it to the TV via HDMI. The USB connectivity works plug-and-play with our laptop. Only reason I didn’t give 5 stars is that the plastic arm feels a bit flimsy compared to the solid metal base—but it hasn’t broken yet!"Purchase Date: April 2025 | Usage Period: 3 months
⭐⭐⭐⭐⭐ Dr. Alan Foster - University Lab Coordinator
"We deployed ten of the Advanced Models in our engineering lab this February, and they’ve held up perfectly under heavy student use. The 2x optical zoom is essential for showing circuit board details, and the A3 capture area accommodates full schematics. Students appreciate the real-time annotation capability during group projects. Plus, the RoHS and CE certifications gave our procurement team peace of mind."Purchase Date: February 2025 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Nadia Khalil - Online Tutor
"Teaching math and science online was tricky before this camera. Now, I can write on paper and stream it live in crystal-clear 4K—no lag, no blur. The Wi-Fi model connects effortlessly to Zoom and Google Meet. I’ve had it since March 2025, and both my students and parents have commented on how professional my setup looks now. Even works well on my small desk thanks to the compact footprint."Purchase Date: March 2025 | Usage Period: 4 months
