Review on 💪 CNC Linear Length Carriage: Powerful Miniature Power Transmission Products for Precision Engineering by Curtis Donjuan

Absolute scrap. First, there are a large number of stickies. You must give the sled a powerful push before it moves. Also, there are a lot of "teeth" which means that as you move the slide you can feel the balls getting stuck and released, stuck and released, etc. It feels like a tire running on railroad ties. They come in unmarked packaging and have no brand name anywhere, leading me to believe they are cheap copies of a quality design or a factory defect that someone picked up off the ground and sold. Totally useless. Made in China, imported from China. That says it all.
