Review on Skateboard 685ZZ 618 685Z 1000085 by Travis Caminiti

In short, they're not top quality, but they're pretty good, especially for the price. I bought them for yo-yos. For those who don't know, modern unresponsive yoyos require very good bearings to function properly. This is a D size in yo-yo terms. I think they will work well for any high speed application within reason. The concentricity is pleasant, there is little play. The metal looks high quality and well made. Can't say for sure, but I think it also has a metal cage (plastic is used in unnecessary bearings). I think they will be good for RC too. My main issue is that the screen is not removable and comes with a small amount of lube. The lubrication in them isn't that bad compared to others, but I'd prefer a light oil or dry lube. I knew before buying that the screen is non-detachable, and other devices of this size with detachable elements have been bad for me, so be careful with this one. I've bought a lot of horrible bearings that are rubbish and it's hard to judge the quality from the listings. That's why I left a review to help others. I like them in summer and I think you do too.
