My new H3 is coming, now i'm locking for a line conditioner, but seems dificult to find a 240w one in spain or europe. I only found surge protectors and Sais, maybe one of these ara enought, i don't know.
do not give in to report your problems to HA. I'm in the same situation. I hope they work in this direction if they want to sell vaporizers in Europe. There may be poor electrical lines in Europe but there are also vaporizers that work perfectly on them.
Sorry i can´t help you. I burned 3 elites and a h.2.2. Herbalaire sendme replacements from Canada in 2 weks, so it´s fast. And I send the brocken devices to Prague. I`m in a special case, because many of the users don't have any problems and still using the HA from 5-8 years without problems...
He say from there
It's normal you can't upgrade your product, but probably, if the Crafty fails in warranty period and a replacement is needed, I don't think they bring problems to change it for a Mighty paying the difference.
