It takes a few runs to break in the bearings, but once you do it runs smoothly. Been happy with this pully unit as a zip line trolly.

Great product. We have had is for 6 months with constant use on a 100 ft zip line. No issues. Warning though, there is not much friction so it moves pretty fast. I had to double the spring buffer at the end of the line to stop my 120 pound kids fro. Hitting the tree. It still doesn't stop me from hitting the tree. I am 210 lbs. Its fast!!!

I purchased this item to replace the pulley that came with a dog run kit. My 100 pound dog has put it to the test and it passed with flying colors.

Like the product as far as the pulley/ rollers are Concerned. The carabiner Is not one I care for. I like the triple or double locking style my self. The product was less expensive then other brands and works well for the speed line application I’ve used it so far. Overall I would recommend the purchase of this item.

The zip line gets stuck between the wheels and the frame pf the pulley. So if kids bounce up and down while zip lining the cable can stuck and wedged between frame and wheels of the pulley. The kids get stuck while suspended and are trapped until I show up with a ladder. With many kids from the neighborhood using it, it is difficult to get them all to not bounce.
