I got one cheap on ebay to pair with my xpro1.
In my opinion it has 2 downfalls, no swivel head (fixed straight forward) and it runs on AAA batteries which limits shots and recharge time.
Other than that I think people are overly harsh on it. Firstly its built really well, feels premium to match the cameras it was designed for. Secondly, people claim is underpowered.. for what? Its not for lighting up a fucking room, its for a pop of light at parties or something. It 's tiny, smaller than any other flash I've used and I can just pop it in my pocket.
If its your main flash, maybe look at grabbing something else but if you know what you are getting and can find one cheap I'd say go for it.
Also if you look online there is free files for a 3d printed diffuser for them. (pic related)
