I do Love my Grasshopper and so far its the best portable vaporizer I have ever used. At the same time it I hat this company. They have the absolute worst customer service I have ever experienced in my life, the worst. I have been going round and round with them and am at my wits end. I love this product, its the best and I hate this company they are the worst. Whatever you do do not buy a grasshopper. I don't know what to recommend but please save yourself a tremendous heart ack and never ever purchase anything from this company. In fact I would recommend that if a company does not have a customer supprot line that you can speak to a live person then do not by a product from that company. If I could in some way distroy the grasshoper company I would. If anyone is good a media please reach out to me, web media, I would like to start a huge campaign to let everyone in the world know how bad Grasshoppers customer support is. Also if anyone knows of a vaporizer that comes close to the grasshopper please advise so I can tell my friends about it and a larg group of people I am connected to on the net, thank you
