Best offer for the lifetime warranty Titanium grasshopper. You have to send it in for warranty, that's like $20 for shipping. New TI on grasshopper website $265. From Reddit: A new device comes with a lifetime warranty that is attached to the buyer's account. If you buy one off someone them you get their vaporizer, but not the hopper labs account (to which the warranty is attached). If you have a hopper but not an account with a warranty you can make an account and buy your own warranty for $45. Again, this is just my interpretation of what a hopper labs rep told me. If you want you can always just email them. They have excellent response times.
