“the quality of the refills aren't like they used to be! 1 filter would last all day when I started buying them, now I have to open a new one before evening. Some of the filters I received taste like menthol, and a few I've received has no thing in them and I I can not smoke them and also I got 1 that is crooked and won't screw on the battery. I saved the ones that were not of the 21st Century quality. I have really enjoyed my smokes, but getting a bad one is discouraging. Thank you, Gail Batson”
