It's a great figure. Not perfect, but great.
The level of detail is fantastic. The paint apps are great - the armor looks far better than I've ever seen on a Jango Fett figure before, and the jumpsuit underneath is the right color. The way the flamethrower was incorporated with the left gauntlet came out much better than I had expected.
The cons? The holsters are pretty chonky. I've heard plenty about wall thickness being an issue with Hasbro's partner factories in China, and this seems to be an example of that. There seems to be a decent amount of play with with holster straps. I know that has limited leg mobility on a number of other figures before. I also had an issue with getting the helmet to sit firmly on the peg after removing Jango's head.
And of course, we have the Fett tax at play. The inclusion of 3 flame effects should not be cause to make a figure like this "deluxe" and charge $25. But this is the state of things. And given the number of additional accessories - especially a loose head? I want to see some in-universe containers included with these world building figures. It helps achieve the whole "world building" concept. And it can help to manage all of the accessories included in these sets.
