Really hoping we can post in the Vamo forum soon. There's a lot of updates needed on the Vamo front.
There seems to be clones going around now that have different electrical components or different firmware. Some people's Vamo's do NOT remember wattage settings. A potential flaw (though there is an easy work around) has been found with the VW after a change of
batteries. Whether all Vamos are effected or just the clones, we do not yet know.
