Really like those. The taste is fresh and sweet and not too intrusive. Also, they're easy to use: slim and handy - no need to prepare the pouches manually before consumption. They really fit well under the lip and are very discrete. The texture is also very pleasant in the mouth and doesn't get awkward even if kept a bit longer in the mouth.
The cans are a bit hard to open though, and also the little container for used pouches is a bit too small and doesn't close well if you stuff it. But these are just minor details regarding the packaging.
