This is an OEM flash pack that's compatible with Canon flashes that have external battery capability. It will speed up your flash recycle times and give you a lot more run time. Sure, there are tons of cheap Chinese made battery packs out there but would you really trust your $450 580ex to one of those? This is pretty much the same as the CP-E3 and CP-E4 except that it only has a 6 battery capability, which means that this one doesn't recycle as fast or last as long but is a little more compact. It also doesn't have the slide in tray, which is why I purchased a couple of CP-E4s, hence the sale. But those are a lot more pricey than this.
