This set has two rare minifigs in, and that makes it a good purchase. I'm sure there will be people that missed out on getting Ventress when she came with the Republic Attack Gunship a couple of years ago and, as well as Savage, having those minifigs makes this set worthwhile.
My 7 year old had no difficulty putting the actual speeder together, and it is used occasionally for missions into Republic territory, but it isn't one of his favourite vehicles at the moment. He does love the Savage character though, and with his horns, he looks very impressive.
Overall, a good addition to any Separatist army.
