I've used their kits a few times and there is usually one or two bulbs that are wrong or are missing. They are very happy to make good on it but I have found it much easier and smarter to just include an extra 20 or so and ask them to throw in an assortment of extra bulbs of various colors. Saves the aggravation of being one bulb short at 10PM and having to wait a week until you get one!
Also, I have started buying 50-100 packs of the standard colors to supplement the kits. After a while, you will have enough bulbs that you can do a whole game without buying a kit. Remember, although it is nice to color match inserts, in a pinch, bright white looks good everywhere! Just don't mix colored bulbs like reds for instance and bright white in the same light design. The difference will be noticeable.
