I was not aware of anything like that but I will look into it, thank you for the suggestion. I am pretty new to this so have some things to learn yet. I have been building and selling these for about 4 months now and has been taking up all my time! 
Just sold a couple more in the past hour or two and almost out of stock (of built controllers, not parts to build more). So need to get back to work hehe. Takes about 1.5 hours to assemble/solder/test each controller once I have all the parts in front of me.
