Mine has just arrived and first impressions are good - it's quite a heavyweight though, no batteries or tank in it and it already seems to weigh more than my Chieftain + batteries + full tank!
Build quality is pretty good - everything is tight, one minor nitpick....the red cover that came with the bundle is glossy and the mod case is matt - not even a nitpick really, the contrast is actually quite acceptable.
First impressions on the JC25-RTA....I like the telescoping top cover - allows for mess-free filling (maybe!)
However, upon pulling it apart, the build deck is identical to the Griffin 25, which worries me slightly since my Griffin seeps from the air control ring - I do like the velocity style decks though.
Fingers crossed the seeping issue won't be a problem for this tank - keep you posted.
Anyway, I haven't powered it up yet, gonna throw on my usual build, fill it and see what happens.
