Trade Mark engine is like one of the worst used car dealerships you've ever been to.
They literally will nickel and dime you to death. Just when you think you got the final price and your set I looked at my PayPal account and they charged me a second charge. Additionally of 350 bucks.
Then you gotta jump through tons of hoops, just to get any money back and you won't get it all. Steer clear of the Dog and pony show going on in Houston at trademark engine!
