Cheap chinese parts that are good for prototyping simple circuits, but not for production or permanent use. They have no datasheets or specs, and likely wouldn't meet them even if they had them. You know what you are getting when you pay this little for a huge set of parts. Don't expect miracles, and buy good parts from a reputable dealer if you are building or repairing something that you care about.
