I've had a great experience with them. Recently orders bulbs for my TAF. I asked them to send me the list for the kit they use so I could customize it, no problem, list sent. I got the bulbs and needed to return a few because I didn't like the way some looked or ordered the wrong ones. no problem there either, they just said send thm back, let us know what you need and we'll send them back (I pay the difference of course, which is fine.). Overall, very satisfied with bulbs and service, couldn't ask for more.
There are a lot machines out there, getting kits right can be pretty tough.
