A total waste of money. a rip off - Mars Trigger Ruger 10/22 Adjustable FRT Trigger

Product is not “Designed for a straightforward drop-in installation using standard tools”. Safety did not work, trigger did not release, rough machining, bolt did not pull back. They don’t answer the phone, they don’t return calls. They don’t seem to have any support people. Do t know what to do next.
