Well after 3 months my v1 Vamo finally bit the dust. The circut board went out. Still not bad for the price though. Wound up loaning a friend my v2 so I guess it's up to the Provari's, SB and picked up a lava tube to play with for a while. (someone stole a co-workers vamo and I loaned em mine). Been wanting to play with a lava tube and now's my chance. So far so good. Like I said the Vamo is really worth it for the price it costs.
