• There are no instructions attached apart from what you see here on the product page, but they are not enough for w good and efficient building (for example it’s not mentioned you need the alternative backplate of the original HG Turn A Gundam kit 
• The mounting piece was not cast properly and missed a lot of plastic, breaking in the process
• The wings do not have a holographic sheen, they are kinda dull and boring 
• Mounting c clips of the wings are kinda floppy and do not keep wings in place securely 

It’s not a bad addition but the low quality shows, unfortunately
