From their web site their kits seem good however you'll have to Google to see user experiences. They give you the set of xenonmatch fog light bulbs which they sell for $30 + shipping when purchased separately. The kits are $150 which is steep even when backing out the cost of the fog bulbs which you may or may not want. The fog bulbs look good though if you want white.
One thing is that all of their kits seem to be 4300K which is a very white color which gives a bright factory color (personally I prefer 6000K which has a hint of blue but 10% less visible light output).
After all of the above, I'd purchase an Apexcone kit from
www.ddmtuning.com . Much cheaper and a better warranty, even on the bulbs. To me, these kits are pretty much the same these days so I shop on warranty and price. I'm curious why you're looking at Hoen.
Also, if you're new to HIDs you need to know about relay kits (I don't use in normal circumstances for a 35 watt kit) and also about reducing glare to oncoming drivers.
