Great packaging and fast shipping. The base is a little bent and one of the guns look to be slightly crooked in the base. The green pedal cable on one of the guns had the plastic cap missing. I was able to test out functionality and so far works great I have not been able to test out the lighting and force feedback because I need to order the wire harness and the power supply. I'm sure it will work. Despite what I mentioned above which I am sure I can adjust and fix. These guns are great and would order again. I noticed there is a little bit of a lag in technoparrot so running alien extermination outside of an emulator and works great. If I get a chance to I will try to post a picture of my finished analog gun arcade cabinet project.
The gun works great on MAME PC version and have been able to get it to work on 'Alien 3 The Gun' on Retro Pie . Looking at config files to get it to work with other games on Retro Pie. But for MAME on PC just a little bit of setup and its up and running. Will probably buy another shortly.
