I just picked up and installed a DDMTuning HID kit on my Winjets today, I went with the H7, 35w in 5000k. Install was straightforward, plug and play.
After lighting them up for the first time, the angle was extremely off but I was able to adjust it with a 8m socket like in this video:

Here's a picture of the cutoff and pic of it installed.
I've used DDM kits on all my cars so far, they have lifetime warranty which is convenient for me since they're local to me.
Output is much brighter than the H11s on the stock headlights, but also depends on how you adjust and angle the lights.
