I haven't had a chance to use this product yet but it seems to be of good quality, I'm using it to create a Polley system tho, so more of a special use-case I guess. I like how it looks and seems to be adequate for my needs

It worked as it should. even with months out in the weather it has performed flawlessly and keeps the kids busy gliding through the backyard.

I guess we hoped to use this for our zip-line. It's not a ball bearing based trolley. It does not run super fast with weight on it. It works, just not the way we need it to.

Using these to replace a much heavier model pulley on flying trapeze Rig. I have done light testing and so far so good.They need to to be packed & shipped properly in a box , not a padded envelope. The first two were damaged but they replaced them very quickly.

Beware DONOT buy the ALUMINIUM WHEEL pully for steel cable ZIPLINEthe cable will eat or burr the pully wheels. For some reason the Q&A and marketing description makes it seem that the lighter aluminum pully is ok for zip line usage it is NOT.ONLY use ALUMINUM on rope i.e non steel cable.

Bought for a zipline, bearings are stiff so it doesn't glide very well. Highlyrecomend getting an all steel version my cable also burred the aluminum pully wheels
