I have a lot of experience with Lava Tubes. First one V1 I ordered had a problem with the button. They were very quick and courteous about replacing it. It worked great until somehow it ended up in the bottom of my pool. Took about a week to find and was dead. I got another for $79 and that worked until I lost it on a roller coaster ride. Next I bought a chrome version which has been flawless in firing and providing joy. I just ordered a V2 in gold for just $49 and am really happy. With my track record of losing mods I think the relatively inexpensive VV Lava Tube is just the right fit for me. I should say one of the counterfeit batteries that came with the initial package I bought still work pretty well.
