Okay but noisy

Worked fine after adding some extra lubrication. Out of the box they were a bit stiff.

Perfect cable routing

Reduced noise significantly in my robotic arm assembly. The V-groove holds the cable securely.

Good value

Quality is solid for the price. One bearing was slightly tight but loosened up after use.
