Good bearings for small hobby projects
I got these bearings to use in various projects I'm working on, mostly made of 3D-printed parts.You get 10 bearings in a plastic tube with a cap, which helps keep dust and contaminants off them while they're in storage.The bearings themselves have two rubber seals (the "2RS" designation). Other types of miniature bearings might have the designation "ZZ" or "2Z", which refers to having metal seals/shields. While the rubber seals will provide better sealing over the metal shields, the rolling resistance is likely to be slightly higher. However, for my use case in hobby projects, this does not really matter.They seem well made, and are the exact size I expected, so I think this set is good value for money.

Seem very good
The proof of the quality will rely on me getting a project finished but, on inspection, these seem perfectly acceptable to me. Nicely finished and true to size, all very freely moving, and ideal for hobbyist purposes.

Good RC crawler replacement bearings
5x11x4mm bearings are one of those sizes commonly found in RC Crawlers. It's always nice to have some backups in case you need to replace one of them. These bearings fit the bill and work as intended.
