*by S***R on Reviewed in the United States on 27 April 2020*

Look for that 'Abec-5'.  It's not that Abec-5 means they are the best made it's mid on the Abec scale.  To me it means they are better for the money by a magnitude than all of the other bottom of the barrel bearings you are likely trawling through now hoping for fast shipping as a prime member.  If a seller doesn't list where said bearings rate on industry rating systems then they are almost certainly low quality.  Also these weren't much more $.  In some or maybe most sizes of these small bearing packs here your not going to find any Abec-5 or they will be over 2x the price, sigh.........
