Yes i have, they are a ACM (ALL CHINA MADE) company, kinda like JG and Dboys but yeah imo dont go for it lol not worth your money , personally i recommend you do not invest in ACM guns, cuz its not worth it, you end up spending more money fixing and maintaining it than if you bought a high end AEG
unless of course you buy it just to throw out the gearbox and put in a drop in systema or G&P gearbox
