Yea, V1.0 was lifetime and replacements were V2.0 which sucked and then came 2.1 which still sucked so 3.0 was born but yes, 90 days. That's my approximate gleaning. I have a nicely functioning v1.0. I don't think a lot changed in the circuit, just the packaging. They were front-runners so a lot of tech is homegrown.
