I have not installed this kit yet but I have installed the H11 kit from the same company and for the price I am happy with it.

If you are in the market for a good, affordable HID kit, this is the one to get!

I just recently installed this kit into my car, so I have no input on the longevity, but the quality seems good. The install however, was a bit confusing as some of the electrical connections were able to be installed two ways. Needless to say I was a bit confused when the lights didn't work correctly and I thought everything was installed right. Also, there is little difference between the high beam and low beams. The kit itself is nice tho and I do not regret buying it.
