These router bit bearings are a good price for a simple product. One of the five doesn't spin as freely as the rest but that's ok because I only needed to replace two at the time I ordered them. For the price I can accept a faulty unit, but better quality control would have earned it five stars.

Misread the measurements and ordered a size too small. The I.D. is 3/16", which doesn't fit any of my 1/4"-shank bits. 3/16" seems like a pretty non-standard bit size---maybe it's used more in CNC applications? Nearly all the router bits I'm familiar with are either 1/4" or 1/2" shank, so I don't know where these would be used. In any case, they seem fine, but they're too small for me to test them out.
