The stove is great. Lightweight, efficient, easy to maintain, and compact. I got the auto ignite version and would recommend it to everyone. I believe that you can purchase the piezo seperate and install it yourself later. I have been using this stove almost three years now and have had not one problem with anything failing in the field. I use it in all seasons. The only reason i gave it 4 stars is because you must have the wind screen. Especially in winter! it increases the efficiency ten fold. I think it would be cool if they shipped with the screen but, eh.
