Overall paso is a great company providing great cbd quality products . The Battery pen can be of better quality found the button fell off on my recently purchased pen . They were kind enough to send me another replacement straight away . Only issue I have is that the cartridges have no labels or markings to tell you which is which so if you have more then one flavour or type of cartridge open then you don’t know which is which . So I would suggest if they can label their cartridges with each different flavour profile or make them easily identifiable this would be great . Overall a good company and great products .
