My opinion on this rda is it is very good. I love that it doesn't get hot and I use pretty hot builds, my only con is the build deck, coming from the goon this peerless deck is a learning curve to build on, I seem to have a issue getting the screws to trap my leads and I am using 6 wrap fused Clapton's with a 3mm ID. I get it to work but I just wish they had designed the deck a little different. But above all this rda gives great flavor and vapor. And it has the deepest juice well I have ever seen. Great job geek vape but version 2 I hope to see some changes.
