I was afraid to order them because of the price (less than 0.50 cents each). Some reviews mention missing some of the 20 seals etc. All my 20 were sealed on both sides. The gaskets looked well seated. I checked the smoothness of each bearing and all 20 were smooth and spinning well. 20 out of 20 were flawless and are now in my new project Tamiya Son Of Wild Willy. (Vintage Wild Willy body mounted on a 4x4 GF01 chassis. UPDATE: I just received my 2nd order of these stocks. 5 stars still stand. I still don't know why some had problems because after checking the 2. of the 20 bearings all 20 still had the seals intact and all rolled smooth. However I did see a mark on one of the outer races that looks like it has been used or at least built into something at some point. But it still looked well out and rolled well. Maybe it's one of the many they test with? Not sure but out of the 40 bearings I got, they work 100% as they should, no cosmetic issues with the small one mentioned Exception with them, specifically 0.45 cents per bearing.
