8320 (with blender jar) is not available as a CH version, i.e. the plug is definitely a Euro plug. The 8300 (no blender jar) has a CH version and you can usually get it (according to the product number). In the meantime, however, it has become apparent that Galaxus is not so careful and has foisted a Euro plug on you for the 8300. If in doubt, take the one with the blender jar. Otherwise, insist on getting one with a CH plug. (All information as of today. If Galaxus changes the product specifications, these details could lose their validity.)

The blender jar is included with the KVL8320S.
With this one, the blender jar is NOT included and in case of a defect, the warranty would probably be handled by Techmania.

This means - as of today - definitely buy the KVL8320S for 519.-. And not the more expensive one with fewer accessories from another supplier...
