Both arms worked right out of the box. Assembly was quick. I had to request a small part replacement and it was handled within 24 hours. Refund policy also looks fair and easy to navigate
I use these arms in my classroom to teach students how machine learning meets robotics. The hands-on experience makes learning incredibly engaging.
We ordered this for our high school robotics club and the students loved it.
The quality of the 3D parts are amazing.It seems sturdy.It took less than an hour to assemble.
