I've been using them since 1992. I've had a vacuum cleaner ever since. The bags are easy to install and easy to see how full they are. Sometimes, depending on what I'm vacuuming, the smell can get in.
I didn't know about this vacuum cleaner at first, no instructions but once I figured it out it's easy to use. As "old fashioned" as it is, it's way better than all those centrifugal extractors, paper filters. It works and it's cheap.
I think this is a fake brand just a Sanitaire imitation. The packaging and the printing on the sachets are completely different from reality and "odor control" is not mentioned anywhere except on a sticker on the back of the packaging.
