Yes, I used the Spark-Lite to light a Tinder-Quick (from the PSK) and a plain old cotton ball. It works very, very well! I'm mulling over whether to buy one or two more of them or simply get a couple more PSPs. The kit is that good.
True, no kit that small could satisfy every desire you'd want in a kit. But it certainly covers the basics. I just recieved my Aqua-Pouches today, and I'm going to see if the 1 qt one would fit in the PSP if I remove the tinfoil.
