It makes it easy to get back in the air quick. This is a very nice charging hub. It charges the batteries very quickly was well worth the money going with a dji product. You could get a cheaper charger, but you get what you pay for. Keep that in mind. This hub can charge up to three batteries at once, as well as having two standard. Usb ports and a micro usb port, so you can also charge the rc as well as the batteries. I highly recommend this hub for all who own a spark Music being able to charge three batteries. The spark remote and my cell phone all at once makes this product awesome.
