Just got my ebay Tugboat V2 clone. This thing is not built very well. Not even close to being a 1/1 clone. All 3 posts have a tiny bit of movement if you try to wiggle them, not milled into the deck but screwed into the deck I guess. Tiny posts and tiny screws, looks more like a toy. It does work though. I've tried both single coil and dual coil builds at around .5 ohms. Any higher than 20 watts on this thing and it just gets too hot, even the drip tip burns the mouth. Dunno about RDAs yet in this part of my vaping journey, have to play around some more I guess. It's alright but it's not blowing me out of the water like I was expecting from watching all the vids I've seen of the die hard RDAers. In this stage of my vaping experience I'm still liking my Atlantis much better, a lot more flavor and a cooler vape. Have to see if time changes my mind.
