I have upgraded to the Go-Go from a Eluma 902, which did help me quit analogs, but the parts were constantly breaking, and the automatic batteries would always flood with noise or wind, then die.
I spent a couple hundred before I got frustrated with it & their customer service and found this site and researched my next PV the go-go. I absolutely LOVe it. The 1300mah batteries last 2.5 days before needing to be charged and I vape all day, my bf only charges every 3 days he is a lite vaper, he had quit entirely until I got the go-go, he tried mine and my new DIY liquids & wanted to vape, so i ordered an extra cone & we each use a go-go. For the price, 49.99 for a starter kit, its a Great! no hassle PV.
I got my first order from cn-cigarette.com which is from the China manufacturer it only took 7 days.
I have also ordered parts and a new mod chopper tank from Eric @ go-goUSA.com . He was just a go-go user who could not find a charger and started his own shop. He has helped us go-go users with adapters and new single parts at the BEST prices around.
