Many have run the ww kit and have not had issues, we diagnosed nearly 90% of the fires as the cap blowing open. I'm not trying to defend the set-up and dont recommend it, but still run it.
Meth can be had in 5 gallon containers for around $55 from a local supplier. Distilled water is around .99-1.99 per gallon. I buy the 100% pure meth and mix it down, I also dye my mix with food die to help aid in leak detection. Its cheaper to go this route.
