Query: Functional but shoddy

It charged my DS just fine, but after the first use I made the unfortunate mistake of pulling it out of the DS by the cord. Apparently the plug that goes into the DS is not solidly fastened to the cord, so the cord neatly separated from the plug, rendering the device useless.Lesson: only buy third-party accessories from name-brand manufacturers, or just be very very careful.
