Excellent bearings. They run smoothly with no issues. They come in little tubes, which is great. Overall, an excellent product.

I needed these for a few of my 3D printed projects and they're working very wellSo far, I've used about 20 and all have been very smoothQuality for the price is on parThey're holding up very wellSize is accurateI'll be picking up the 100 pack as soon as I have more projects that need them, for the price, they're tough to beat.

I frequently tinker on random projects, and often need bearings for various purposes.These are perfect. They are consistently sized, and work great.I wouldn’t recommend these for making a super long-spinning fidget spinner (the lubricant in these is a bit thick I guess), but if the spinner is heavy enough, these could work for that too.

These bearings come in plastic rolls and for the price to quantity these have very good value. Useful in all manner of projects, these bearings roll very smoothly. However, they aren't completely free moving and it does take slightly more than expected force to spin, so lighter projects like fidget spinners may not work as smoothly as intended.

These 608 bearings are fine. They are not the best quality compared to the ones I got that are made in Japan and cost $15 a piece. I did not expect them to. For budget bearings, these are decent and are perfect for a DIY project or replacement.

Useful for all kinds of projects. I intend to use some of these to make a router sled to flatten wood. Super great price for 100 bearings. I haven't checked all 190, but the ones I checked all run smooth. Feel like good quality bearings.

They come well-protected in plastic tubes. The bearings have been smooth rolling so far. I've used some for a 3D filament respooler and some wheeled toys. I plan to make a router sled for flattening slabs next and these should work well! No defects in the ones I've tested.
