I liked the price and build quality, apart from the fact that it's made to order for Sony (not many flashes come with a Sony shoe mount). Wireless connectivity makes it even more versatile. But you need to get a little creative to make it work. I also don't like that stupid diffusers keep falling off! Seriously how difficult it would be for Mike to scale them down to size before they go to market. It looks like you are using another brand of diffusers.
