Too bad, there isn't a "0" star, so I have to select "1" star, DDM Tuning sold cheap products with defective parts, they don't stand behind their products, horrible customer service. *** PLEASE STAY AWAY*** from this company, especially the Huntington Beach branch. Don't recommend you buy from them, you'll regret it. I bought 2 complete sets of HID (D4S & H11) with a life time warranty in Huntington Beach store, after few months, 1 D4S bulb was dead, I brought it in, they gave me a hard time for exchange with too many excuses, they recommended to buy another pair, why would I have to buy another pair while my HID bulbs are under life time warranty? I gave up on that one and ended up buying another pair from somewhere else. Recently, a set of H11 were acting up, I spent more than 1 hour driving from my house to the same store (Huntington Beach store), hopefully they will give me an exchange because those bulbs are under lifetime warranty. The sales person (Stefan) gave me hard time and excuses for exchanging those HID bulbs, he said it will take him couple hours to test the bulbs, I don't have couple hours to stay for that, I asked him nicely to have another pair because they're under lifetime warranty, he said "NO". Again he recommended to purchase another pair, they always want to sell, not provide a good service. I'm so dissappointed, I just wasted my time and money for DDM Tuning products. Salesman (Stefan) at Huntington Beach store has an attitude, bad customer service skill , he acted like he owns that place, don't have much knowledge about the product. Don't waste your time and money with DDM Tuning products
