I got these fidget spinner bearings a couple weeks ago and they are pretty nice.
Although these bearings are noisy they are well worth the price ($8.99). The spinner in the picture is relatively light to some of the others I have, but still gets a decent 2:30 out of a good spin. The 2:30 spin isn’t the best but I still think the price being less than a dollar a bearing makes them still worth it.
Overall for the price these bearings are worth getting, although you could go for the more expensive ceramic or silica nitride to get better spin times.
If you are interested in getting this pack of bearings you can find them here on Amazon.
