I have used Blazers for many years. It is simply the most reliable burner. I use it to vape various medicinal grade oils and concentrates and it works great with all sorts of devices and has completely replaced my big bud as you can't tip it over! It is also very good in my first-aid kit, it is reminiscent of the table lighters that our grandparents loved. I also find it easy to fill and very economical.
