Review on High-Quality 12 Pack of 606 2RS Ball Bearings for Industrial Use by David Bowens

Good value for simple projects. I wouldn't use it on a skateboard or scooter as there is no joke rating and there seems to be too much play, lubricated or not. But for simple projects where a bearing would improve things, I recommend them. I used this law for filament guides and spool rolls for my 3D printers. NOT RECOMMENDED for replacing bearings in tools or motors. Benefits: Easy removal and replacement of seals. Accurate dimensions, no rust inside and out, rolls smoothly at low speeds. Cons: Contents dripping in oil when unpacked, oil hides dried grease but degreasing and sonication removed that, slight play in unlubricated bearings, rattling noise at 300rpm (lubricated, no load).
