I would love to have one of these. I applaud the use of all metal and glass but I tend to bite the end of my tanks. Just for that reason I need a plastic tip so that I don't destroy my teeth. If I ever get over that habit would love these. I use a mini t3 that I modified with an SS wick and it works great.
I hear you. I don't like metal drip tips either, and don't use them on my Cobra at home, but after breaking a couple of Drunker and Nova acrylic tips from carrying them around in pockets, I've gotten used to them as long as I don't let my teeth become involved.
I ordered two Protanks from gotvapes and they arrived today. First impression is that I am quite impressed. I really like the airy draw. It's so easy to inhale. The vape is cooler than a top feeder, but if you like a relatively gentle, mild vape it's great. I still get a decent TH at the end of the draw. For the price I am extremely impressed with the build. If it passes the test of being carried around town with me on a bicycle without leaking, it's a keeper!
BTW, I didn't pull the top coil or anything because I like it fine as is. Maybe I'm not very fussy... As they say, everybody's mileage varies...
