The delivery was fairly quick, all things considered with pandemic-related delays at the time. The packaging was appropriate considering the fragility of what was bought, and this charger on its own is a great piece of kit! Remove the spring-loaded half of the battery contact in your GBA, slip this in, and it just works!
Has an on/off switch for storage to slow decay if the battery and really extends the battery life of a GBA. Strongly recommended!
