Have the lighting coal for a few days and must say it is really great! 5 step control and very quietly clicks only briefly when it switches on and off but this is normal The coconut charcoal which I use is completely ready for what I think is very positive in felt 5-10 minutes. einzigste shortcoming that I have with this is the disgusting stench Kohleanzünder on first use but what lies back after 2-3x use of Kohleanzünders.
I can say nothing about the life, but will update my review in due course
