They're what the box says, masterpieces.
Both Ravage and Rumble arrived in mint condition, packaged very well. The box itself also in mint condition which is great as I also save boxes.
Their transformations from cassette to robot mode might seem tricky at first but they're pretty easy once you do it a few times and they look great and premium in both modes. Rumble's gold accents on his chest being standout, as well as Ravage's mini-rockets being a very nice silver and they're also attached to him already unlike his older figure so no having to tab in his mini-rockets once you have him in robot mode ; less small parts to potentially lose.
The only 'flaw' [more of a nitpick] is that Rumble might be a bit tough to get inside his cassette case, it's a tight squeeze for him but he does fit. Ravage has no such issue fitting into his case. Overall, recommended.
