Everything OK. Depending on lighter "pfusts" a little out next. The 'problem' but I know already from other gas bottle. But if you filled in batches (as 3-4-5 times) and not constant remains top, the holding in the framework and (in my opinion) the lighter fills better / full. However, since 12 bottles are for me as a private person too much, I share in the families, friends and neighborhood district who have been looking forward all because = value = great! The bottles could be a bit better packaged, because different cover in a box 'lying around' and the adapter together with it (why only 4 stars), but for the price, I read that then just themselves together and put the parts back on it and from it ;-) \ Still - happy again. Thank you! = Buy recommendation!
