DDMTuning quality has really dropped over the last few years, I have ordered 4 kits from the over the past 3 years and all of them had problems, especially with Ford. My 2011 ford edge with the Retrofit Source kit is working perfectly after 3 years. I would highly recommend them, they are a little bit more expensive then ddm, but way better kits. I have the 55 watt kit from retrofit and it works great!
